Bitcoin does not like this because, just like certain wealthy elites control fiat system, they could try to do thesame thing here if Bitcoin community start trusting or depending on them.
The "wealthy elite" of course can buy into Bitcoin and get some influence, and this is a bit unavoidable for an asset with a good ROI. But there are two catches:
- several thousands of small retailers can be as strong as a big whale,
- and the early cypherpunk adopters were often not that rich, at least not super-rich. They are the ones that most benefitted from BItcoin's rise, not the wealthy elite (with few exceptions).
I don't know who is the single biggest Bitcoin owner (besides of Satoshi) - it's probably not Saylor because in his case "his" BTC belong to a public company, and there the ownership is distributed (in a quite complex way) amoung the shareholders. So they have probably not a "single will" when it comes to where Bitcoin should evolve to.
For example, let's have the following thought experiment: Bitcoin wants to incorporate more privacy with a softfork. That would increase the potential benefit for the users and thus could increase demand and market cap.
Thus most retailers _and_ smaller ETF investors _and_ smaller Strategy shareholders support that change for purely selfish reasons, because they think the price could go up.
But the ETF and treasury companies and some of their larger investors are against the change because they fear tighter regulation and even trading bans (Bitcoin would become a "privacy coin".) And even if this increased the Bitcoin price and also the potential group of investors, they could be forced to close that business section or at least move their headquarters out of the US or Europe.
I only posted about that possible conflict to show that the coins controlled by ETFs and treasury companies do not necessarily behave like "single big investors". So the sheer amount of coins (2-4 million) controlled by big treasury and financial investors can be misleading and exaggerate the influence of "big entities" or "whales".
