As we navigate the digital world, we rarely receive truly free services. Platforms such as social media, search engines, or “free” apps charge us with our data and interactions. These companies collect, analyze, and sell our personal information to monetize it and optimize advertising.
The expression “if you have not paid for the product, you are the product” it was popularized by Tristan Harris, ex encargado de ética tecnológica de diseño de Googleas a denunciation of how big companies use our data to create campaigns increasingly aggressive and customized.
Since 2010, Harris has warned about the practices of tech giants like Facebook, Instagram, and Pinterest, which share users’ behavioral data with advertisers to generate revenue. Among the most common data monetization mechanisms are:
- Targeted advertising
Browsing data, interactions, and preferences are turned into audience segments that advertisers buy to reach the most receptive users. - Pay-or-Tracking Walls
Some publishers and platforms (e.g., Meta and various European news outlets) impose walls where users must choose between paying to avoid tracking or consenting to exhaustive surveillance—potentially increasing ad revenue by up to 16.4%. - Selling Insights and Profiles
Organizations, startups, and even NGOs collect and analyze data from “free” users to generate valuable reports that are later sold to third parties, without needing to share raw data.
Privacy Implications
We often don’t understand the full extent of what we’re giving up. We lose control over our personal information, which is exploited by engagement algorithms to maximize our attention. These systems prey on psychological vulnerabilities—instant gratification, fear of missing out—and then “sell” that time and attention to advertisers.
Moreover, pay-for-privacy options reinforce inequality: only those who can afford it avoid tracking, turning privacy into a privilege rather than a right.
The role of data brokers
Los data brokers son empresas especializadas en recopilar, fusionar y vender información personal procedente de múltiples fuentes: redes sociales, registros públicos, historiales de compra, geolocalización y más. Aunque el usuario no interactúe directamente con ellas, su huella digital queda en manos de estas firmas, que crean perfiles muy detallados (edad, intereses, nivel socioeconómico, hábitos de consumo e incluso posibles vulnerabilidades).
These profiles are then sold to advertisers, financial entities, and government institutions, without the user’s knowledge or control over who accesses their information or for what purpose.
Dark patterns
Los dark patterns son técnicas de diseño de interfaces que manipulan la toma de decisiones del usuario para beneficiar a la plataforma, no a la persona. Algunos ejemplos:
- Deceptive Consent: Pre-checked boxes for cookies or subscriptions.
- Option Overload: A highlighted “accept all” button and a hidden or multi-step “reject” option.
- False Urgency: “Last chance” messages that pressure users into sharing data or subscribing.
These practices exploit cognitive biases—like urgency and loss aversion—undermining the user’s ability to give informed and free consent.
Psychological and social effects
The monetization of attention and extreme personalization impact our mental health and relationships:
- Addiction and Distraction: Algorithms designed to maximize screen time can lead to constant interruptions, reduced concentration, and procrastination.
- Social Comparison: Ongoing exposure to idealized versions of others’ lives creates anxiety, low self-esteem, and feelings of inadequacy.
- Echo Chambers and Polarization: Recommendation systems reinforce pre-existing opinions, fueling misinformation and filter bubbles.
Looking Ahead
Technological evolution brings new challenges and opportunities for privacy:
- Self-Sovereign Digital Identity
Iniciativas basadas en blockchain permiten al usuario controlar y compartir solo los datos esenciales con entidades concretas, sin intermediarios. - Differential Privacy and AI
Anonymization techniques and federated learning promise AI models that don’t require centralized private data. - Emerging Regulation
Leyes como la Digital Markets Act en Europa buscan frenar el dominio de los grandes ecosistemas digitales y proteger la competencia y los derechos de los usuarios.
Pasos para una mejor higiene digital
Adopting good online habits helps minimize risks:
- Scheduled Disconnection
Set aside times without notifications or social media (e.g., during meals or an hour before bed). - Cookie and Tracker Management
Regularly review and delete cookies, use extensions like Privacy Badger, and adjust browser privacy settings. - Minimal Data Sharing
When registering for new services, provide only the essential information and avoid sensitive data if not necessary.
Practical recommendations
- Review privacy policies
Read and adjust app and website permissions to reduce unnecessary tracking. - Choose Privacy-Focused Services
Plataformas como Signal, ProtonMail o DuckDuckGo ofrecen modelos basados en suscripciones o donaciones, sin vender datos de usuarios. - Use Tracker Blockers
Herramientas como uBlock Origin, Privacy Badger o navegadores como Brave reducen la capacidad de perfilado de audiencia.
Conclusions
We live in an age where the attention economy and personal data exploitation fuel much of the digital world. Platforms claiming to be “free” often hide business models based on constant tracking, behavioral manipulation, and monetization of our most intimate information.
The mass collection of data, the rise of data brokers, and the use of deceptive persuasion techniques (dark patterns) place users in a vulnerable position with no real control over their privacy. This issue affects not just the tech space, but also mental health, decision-making, digital equity, and the quality of our social interactions.
In this context, it is urgent to understand that privacy is not a luxury or secondary concern—it is a fundamental right that we must actively protect. Just as we safeguard our physical belongings, we must also protect our digital identity.
Te invitamos a reflexionar sobre el valor de tu información personal. Cada clic, cada búsqueda, cada “me gusta” dice algo sobre ti, y ese algo tiene un precio. Begins to learn more, adjust your privacy settings, choose services that respect your rights and, above all, to question what we consume and how we consume online. Privacy doesn't defend single. Depende de nosotros, como usuarios conscientes, exigir mayor transparencia, rechazar prácticas abusivas y apoyar modelos digitales más éticos. Ser dueños de nuestra información es el primer paso para ser verdaderamente libres en el mundo digital.
