Pay or have ads is fine by the EU’s DMA law too. What isn’t fine is the collection of user data without consent. Facebook can show all the ads they want, but if they collect user data to target those ads they need consent.
Think about radio or TV advertising - those aren’t targeted at specific people, but rather they’re targeted based on what channel, time of day and TV shows that they’re around. Meta can do the same stuff, but they just don’t want to give up that lucrative user data.
I was making the point that ad-supported services have been financially viable for centuries without needing to invade personal privacy, and that governments have been regulating industries for even longer - and at this point, your personal choice doesn’t really matter. You might be perfectly happy to eat food cooked in an unhygienic kitchen, for example, but enough people have been harmed in the past for food hygiene regulations to be commonplace worldwide.
