Decisions like this only hurt Fediverse as general. They become like Reddit where wrong opinion can get you banned, which is main reason for Reddit being shit. If they continue to blacklist instances just because they’re not locked down for the sake of someone not saying N-word, they will eventually become just normal forums (and probably dead).
Safe spaces don’t even exist in real life and people should just stop trying to censor everyone. They’re too sensitive for everything and should finally learn to ignore all insults, etc.
It didn’t change the repo. F-droid has always slower updates, because they’re compiling every app themselves. Izzy is release directly from app developer, so it’s newer. I’d stick to F-droid, so app dev can’t push anything malicious in the official app build.
