So any web host that uses cPanel should be a good thing. IMAP for mail, Caldav for Calendars and Cardav for contacts. It’s what I use anyway and haven’t had any issues
The OS itself is private because it’s DeGoogled. I also installed GApps because I wanted the convinence of the App store and core feature I’ve been used to for so long.
I also knew the moment I did the google-fication privacy was out the window.
I was fine with LineageOS and would happily go back when my Pixel7a becomes EOL.
