Within a week I will take my phone number out of Google Voice. I plan to change emails in the coming months as well. I've started to do regular backups of my Google Drive. I've also started to do any searches on controversial topics in Firefox on DuckDuckGo. If any of my side projects become valuable enough, I'll probably move them off GCS as well.
I'm a little weird in the way I think, so maybe I'm the only one so concerned. I'm probably too paranoid. But sometimes I lose a little sleep thinking about the potential consequences of Google randomly closing my account.
