On my android phone:
My own launcher
My own keyboard
My own sync tool for local net
My own net tools to WoL some devices on my lan.
My own tool to control 3 proxmox servers
My own tool that parses groceries slips
My own tool that keep tracks of my vehicles events/lifecycle/purchases etc.
If they break my launcher/keyboard and my ability to use my phone in my customized way, they will NEVER see me as a client again. None of these apps are in the Play Store, they are signed with my own signing keys, which have never been uploaded to google, in fact, no google account is linked to these apps. These apps are also privacy-oriented (even the keyboard, I ship a 1mb dictionary with and it learns my own words, never transmits anything).
I will not give google my ID , neither Persona or anyone else. I'm very happy to go back to using bank card + chip + pin than use google wallet. Trust me I will walk away. I already move 4 family members off of Windows in the last 2 years, I will get them off google too.
