Note that even GrapheneOS no longer supports the 5a, since it is no longer getting firmware security patches. You’ll need to install an archived version of GrapheneOS, or go for something else like LineageOS.
With LineageOS, you’ll continue to get OS patches, but you’ll be stuck with an unlocked bootloader, so there’s a security tradeoff there.
Absolute nothingburger.
From F-Droid’s statement (emphasis mine):
They’re not blocking any fediverse apps that you can use to connect to any server.
Feel free to use any Lemmy or Mastodon client to connect to any hate-filled instances your hateful little heart desires. If you don’t like that some apps have built-in blocklists, use different apps, or modify them. That’s the beauty of open source.
Do what you want, just don’t expect the rest of the world to amorally do it for you. This is perfectly in keeping with open-source philosophy.
