Maybe I'm a pessimist, but I thought more people would drink their kool-aid. Especially on Twitter, where I see less technical competence than here; many people there use centralized exchanges and often don't run nodes, so I wasn't expecting them all to understand the issue with Chainalysis and blacklisting. So I'm pleasantly surprised. Really good to see.
I wouldn't hold your breath. The people being most vocal about this are obviously the people who are disgusted by it, and so those are the comments you are most likely to read. The people who shrug their shoulders and think "Meh, I don't care if Wasabi are spying on me" are unlikely to make a Twitter post saying "Meh, I don't care if Wasabi are spying on me".
So in my opinion, no matter how many institutional investors they attract; the product will fail if it has no users.
Here are some tinfoil hat thoughts: Maybe institutional clients who want to use Wasabi
know they will get zero privacy in any true sense of the word, since Wasabi is working hand in hand with blockchain analysis companies to spy on their users. Maybe institutional clients don't care if blockchain analysis firms, the government, various three letter agencies, etc., can see everything they are doing. Maybe all they want is to be able to hide from the average user using a block explorer.
Look at institutions like Melvin Capital, Robinhood, or Tether. Maybe institutions don't want the average Joe to be able to identify their cold storage wallets and make a Reddit post pointing out that they are running a fractional reserve system. Maybe they don't want the average Joe to question why they just sent large amounts of bitcoin to some private wallets while freezing trading for regular users.
They don't care about actually privacy which requires a large user base and anonymity set; they just want to mix their funds with some other institutions just enough so the average user can't quite see all the shady things they are doing behind the scenes.
