My biggest issue is there are some people I really want to follow who do youtube unfortunately. Other than that, I could see moving off the grid completely more or less.
I do toy with leaving Youtube though and just taking the hit, would be nice to not participate in ANYTHING the big tech companies produce.
I love F-Droid, a lot of useful apps and good gems for games on there. How do you like Lineage? I wanted to install it when I first got my last phone, but it was still unsupported on the galaxy S8 at that point. I stuck with the stock OS and put in NoRoot Firewall to block all of the system google and samsung apps from phoning home.
