In my understanding, the metrics tracked by just having Google Play services are pretty minimal.
It's more like an API between your phone and apps you install through it, and the permission system for apps has improved immensely over the past 5-10 years. As I see it, it's more like a firewall.
If you don't want Google to know which apps you use and how much, you can go full custom, but that's a bit too much tinfoil for me.
The tracking is mostly from web browsing. If you use Google Chrome, of course you can expect to be tracked based on browser history, cookies, etc., like most other browsers.
If I wanna do something in private, obviously I won't use Chrome or a builtin browser.
I'm sure they're hating that 1% of their users is spamming /r/place with bot visits, but I think you have to realize that there's no "fight" to be won and reddit definitely isn't facing any type of demise.
If you like Lemmy, help improve it and stop talking about reddit.
