It's obviously bad when "real" data like full names and credit card info leaks, but most data companies collect is probably email address and some anonymous things like which buttons and when the user clicked.

Nevertheless, such data collection, tracking and telemetry is considered quite bad among power users. I don't support those practices either. But I'm struggling to consolidate my arguments agaist data collection. The one I'm confident about is effects on performance and battery life on mobile devices, but why else it's bad I'm not sure.

What are your arguments? Why is it bad when a company X knows what anonymous user Y did and made money on that info? What's the good response to anyone who asks why I'm doing the "privacy things"?

So, I’m moving to a new phone and revisiting a lot of accounts, apps, and settings.

When it comes to things like location history or ad personalization or whatever, is it even worthwhile to turn it off? Am I really supposed to believe that because I have some toggle off that Google suddenly doesn’t track where I drive on Maps? Like if they are going to be tracking me, which I assume they are, I might as well be able to see it to rather than have it exist in the aether somewhere where the info is attributed to me but not viewable in the UI.

Even with ads, I know shadow profiles are a thing, and that they definitely have data beyond what they show in the UI, so might as well opt in there too right? Plus, the non-targeted ads I get are basically porn-tier ads or stuff for gay men.

What should I do here? Move into the woods? Feels like I can’t win.
