I can see cause for some concern. But I'd be more worried if they were conventional commercial banks. VanEck and Bitwise are more to do with asset management, brokerage, etc. Plus, they're seemingly on board with the general concept of Bitcoin and have made it a central pillar of their respective business models. If they now rely on Bitcoin, it makes sense that they'd want to contribute to its continued development. I'm confident the community are vigilant enough to notice if there were any sudden changes in approach or direction for Bitcoin development and would act according. It's a potential conflict of interests and transparency should help ensure it's only ever potential.
If Bitcoin core development is the government priorities it should cause concern of course to crypto enthusiasm. I had the believe that anything in the world can be manipulated until bitcoin came into existence and gave me a reason for doubt. Yet, the strive to remove decentralization for bitcoin entirely never sees to end. It all started when the rich tend to put so much money into bitcoin in order to manipulate the sea so that it sails towards their direction. Now the banks which has central authority has added more to these issues. My greatest happiness is that they cannot manipulate the total supply, the price directly and the anonymous nature so bitcoin remains an asset that is uncontrollable.
