Abbreviated subscriber counts are very bad, I can't see my favourite creators reaching their target milestones, there's no hype anymore for when a creator is close to hitting their subscriber milestone because their community cannot see it.
That would be a good idea but it would be nearly impossible to successfully move some of the YouTube community to an alternative site. I would be afraid to do that. Also I don't think this is a major concern that would force me to move to another site but I know what you mean
