All of the "greats" are completely disappointed with the path Bitcoin has taken lately. It's now even worse with the institutionalization of BTC. "Wall Street" has all of the cards to manipulate Bitcoin to its own benefit. Instead of going against the existing financial system (something Satoshi meant to avoid in the first place), Bitcoin has "bowed down" to it. The future is unpredictable, so I'd hope for the best.
Weaker systems are subverted more quickly. Idealists can be disappointed if they like, but it doesn't change the fact that sensible people came to a sensible conclusion. Institutional investors would have gotten involved regardless of how scaling was handled, so try not to conflate separate issues.
