all I can say is a lot of that is FUD.
I would suggest you come over and talk to users of the ecosystem and look onchain for yourself.
Hive is making itself a walled garden and other chains are passing it by.

InLeo has built a true Hive DEX on top of Maya. And onboarded another crypto (Dash)

What have others done? Complaining about onboarding is needed but never do anything about it.

As far as SPL powering up Hive to get approved that was after the DAO was called out.
What have then done since then ???!

Etc etc etc.

Basically engage with the community or listen to FUD.

You choose. But my many years on Hive. I have not seen large accounts care about the chain but instead of being a big fish in an ever shrinking pond and just blame others.
