I think this is what’s happening.
If Google loses appeals, Mozilla (and many other browsers that rely heavily on getting their revenue from Google), will have to find new ways to generate revenue. Unfortunately, they seem to be looking for the easiest way out, and that’s selling out their users.
I use Bluebuild to create a reproducible system, plus a post-install script to handle other post-install tasks such as setting up initial preferences.
Also Vorta to backup files and settings to external HD, plus OneDrive Linux client to sync files and settings to cloud.
