There are other banned parties as well (such as the SRP, which was the new NSDAP basically), having large overlap with the AfD. It’s not bad for democracy, if the requirements for banning are clear and enforced equally.

Peertube is the obvious candidate, but I’m not sold on the content.

I use nebula.tv, many of the creators I like are there too. You pay somerhing, but their business model is not too bad imho.

Floatplane is somewhat similar, but LMG is involved, which I don’t love.
