Fedora. I’d avoid Ubuntu and its derivatives like Pop! or Arch derivatives. I think Arch is fine, especially if you know what you’re doing, but Arch derivatives in my experience are much less stable than for example Ubuntu or Fedora.
But seriously. Fedora. It’s the best. Ubuntu is actually fine too but Blue > Orange
I block advertisements because I don’t want to see any advertisements. They are poison for the mind and I want to eliminate any form of advertisement I can control. Obviously you can’t avoid a lot of it - but I can definitely avoid it in my web browser.
I would prefer a subscription based model or a donation based model. For example Wikipedia or Lichess I’ve donated to because I believe they provide a good service and show no ads. Or for example Kagi which is a search engine that charges a monthly fee.
