It's like someone hasn't even picked up a phone in the past decade. Nearly every app on your phone would have been considered spyware or adware just years ago.
Pretty much the only things on my phone that aren't adware or spyware are free software apps.
That's why I have only few apps installed and if it's possible I opt for the paid version. (I do appreciate Fdroid though)
Still, I think it used to be much worse or at least more obvious in the early 2000s. At that time Shareware was still a thing and it was normal for installers to add completely unrelated 3rdparty software. Probably that's also half the explanation why Windows used to be so unreliable, half of the ecosystem around was just random stuff.
