Bitcoin is a movement that attracts "The Cabal" to where the people are. Currently, we now have Black Rock and the largest asset managers having investments in Bitcoin, and Trump and other politicians talking seriously about Bitcoin. Ten years ago suggesting that that would happen would be laughable.
They do not want to miss out that is why they are now coming into Bitcoin. They know the potential profit that they can make and have bad motives of controlling the market that is why they are attracted to Bitcoin but they can not succeed.
I don't think their reason for trying to embrace bitcoin now is because they don't want to miss an account, but it could be because they have tried all that they could to control it, but it all landed to no avail.
The only option they are left with is to drag it closer to themselves and see what percentage of the market can be under their own control, which can only be achievable if a large number of holders are making use of a centralised system. If not, all they will still end up doing is watching the market, buying large volumes if they can, but they can't have their hand in controlling even 10% of the market movement.
