Imo one of the reasons why the protest on Reddit has worked so well in comparison to X is because of the way content is presented. Whilst X didn’t really care about people leaving/protesting, Reddit was extremely affected by the blackout (even if Huff played it down) because the content that was left was trash and people were forced to move or boycott it at least)… There’s just no comparable force to the subreddits on X that could affect everyone’s timeline so much that they would be forced to stay off it.

That being said, there are lots of more reasons for why X hasn’t died (yet)
