Don’t get me wrong, I am all in for F-droid as well. If one day all of the privacy-enabled apps I use could be found in F-droid, I’d be a happy camper!
Still, since you dropped the 60k number (of apps available in F-droid), let me put that in perspective: Play Store contains 2.7M apps (that’s 45x more). Among these 2.64M apps that can be found in Play Store but not in F-droid, not all are evil/violating your privacy/useless.
Let me name the one blocking example for me: Signal messenger. I think I understand that Signal is not available in F-droid due to (in my opinion) bad decisions taken by Signal’s developer and maintainer, so not F-droid’s fault. And probably this is going to be the case for many apps, where maintainers do not want, cannot, or do not have time to publish on F-droid in addition to Play Store.
So yes, F-droid is great, and I do hope it gets to become the number one alternative to Play Store. But this is not yet the case.
