Maybe it’s unlikely for this to happen, but I wonder if it’d be possible for yt to go down like reddit did. Yt makes a series of bad decisions, so a lot of people move from there to similar platforms. The other services don’t have much content right now, but from what I here, neither did Lemmy before the “exodus.”
I get that reddit and youtube are very different types of platforms and that the whole reddit thing happened because of pretty specific circumstances, but idk, maybe something vaguely similar could happen.
