1Good afternoon, and welcome to this lecture on the ethics of collecting and using personal data.
2Every time we use a phone application, we leave behind traces that companies can gather and analyse.
3Most users click the consent button without reading the terms, which raises serious questions about agreement.
4Some argue that people freely exchange their data for convenient services, so no harm is done.
5However, further reflection reveals that genuine consent requires real understanding, and such understanding is rarely present.
6It was not the collection of data but its resale to third parties that caused the greatest public anger.
7A famous scandal was initially reported as affecting thousands, though later investigations suggested millions of users.
8Contrary to the company's first public statement, the personal data had not actually been deleted as promised.
9Moving on to regulation, Europe introduced strict rules, while other regions preferred a lighter approach.
10What I want to emphasize here is that laws always lag behind the technology they try to govern.
11A concrete example is facial recognition, which spread widely before any serious debate had occurred.
12Next week, we will discuss whether anonymity online is a right or merely a preference.
