Since karma isn’t tracked, I don’t think it’s a real big deal having a negative score comment. But since there are people who care anyways I think the downvote does exist, it can suppress people posting certain points of view lest you anger the tankie triad
YouTube still offers them a service in directing them new viewers. The big creators all lose viewers but YouTube funnels replacement views faster than they lose. They could host their own videos but they are gonna see very little growth without Google either in search or with YouTube as they start to lose the base that followed them.
They also won’t be able to negotiate as good as rates for pre-rolls or in video sponsorships as if they were on YouTube.
The only real alternative would be to band together like the creators that are a part of nebula are doing. Hosting on peertube really isn’t an option unless you are independently supported and you are doing it as a passion project and don’t care about audience growth or retention.
