Same here, only one app, Anki, took the time to inform me they had changed their privacy policy (although they didn't block my account before I accepted the changes).

I don't think they have less trackers. I think it's even easier to unintentionnaly add a tracker to an app because some of them come with dependencies when you're not careful. See https://reports.exodus-privacy.eu.org/reports/ for some reports on what tracker typical apps use.
