I share some of your concerns. Bitcoin is indeed becoming more institutionalized, and many new entrants are really coming just for the sake of profit, ignoring the philosophy of decentralization. However, this is an inevitable growth stage: mass adoption always requires compromises.

The main threat is not the loss of decentralization technically (miners and nodes remain protected), but a change in the culture of the community. If privacy and independence cease to be values, Bitcoin risks becoming just "digital gold" under the control of institutions.

Governments will push, but open source and a distributed network are serious barriers. It is important that the community does not forget the original principles. As long as there are those who defend them, there remains a chance to preserve the essence of Bitcoin.
