I'm from a developing country, where even people working as devs/engineer prefer apps with ads over paid apps. I think the privacy argument is looked at from a wrong angle. Not everyone can afford to pay for a subscription or even a one-time fee. Especially, if you're from developing parts of the world. If there are a couple of ads which subsidizes something that is otherwise unattainable for someone, I don't see why that is bad.

What's the worst thing that could happen from Google tracking me across the web could? Show me a couple of ads that it thinks is relevant from history? I don't see why that's the end of the world.

While I do believe that there should be transparency in what's collected and how it is used to prevent misuse, some of the pro-privacy arguments seem too extreme. I'm open to other views, of course
