I see some core team on this thread, so just wanted to say THANK YOU! Awesome job! Keep fighting for the users!
I'm totally the wrong person to offer recommendations on mobile, but so far it works very well for me, but then, I use almost no third party apps, and none of them are Play store only. My only complaint is the hardware (outside of their control).
So then what's the point of having a Play Store without Google Play services?
I am personally more than okay with using the official, proprietary GP services from time to time if they abide by the same rules, especially that I can make these rules as strict as I want.
