I now have no Google or Microsoft accounts. Only connected to Google through the extensions for Brave, and to Microsoft through DuckDuckGo.
Wish I could happily put a No Google blocklist on my Little Snitch, but alas, still need some of those connections to go through for reCaptchas and stuff. But hopefully soon 
Made a shortcut on iOS to switch quickly between ProtonVPN (Netshield) and AdGuard DNS, so that untoward connections are blocked most of the time.
