I hope you dont also own some google router or even better, "home security" device. This would make it a real pain. I am explaining this to people since the birth of gmail, but no one listens.
Let me think for a moment, what would happen if google does this to me...
[x] No google email (I have my own mail server - it is just a $90 motherboard with onboard cpu with disks)
[x] Modified ROM, no google on android
[x] No google cloud (Nextcloud is just fine, for virtualization I have bhyve. They are both just great)
[x] No applications bought from google play (If application doesnt provide "off google" licensing, I am not buying it - voting with my money)
[x] No content served by google (If I want to share video, I just upload it to my server. No annoyances about copyrights or anything else. It just works.)
[x] No data whatsoever stored in google ecosystem (actually actively fighting against them storing any information about me)
Hm, looks like - nothing?
