Yea, I hear you too, and of course this the prerogative of any individual or team working on a project.
But just to point out some of my own experience from spending a couple of years trying to find technically-focussed people to build interesting stuff for my own project; the ones who I've come across haven't been able to find much investment/employment at all, and instead have been surviving by resorting to building for shitcoin projects. Exceptionally talented people who should have no problem finding a stable place in this ecosystem. I've been involved in tech for 15 years, dev/support to board level, and one thing I'm certain of is that counter to the popular narrative, exceptional developers are extremely rare, and letting them go work for the competition is a strategy that won't work out well in the long term. I think if what you're saying is true, they should maybe consider that being so insular may be doing damage.
