I saw a controversy recently in an open-source project where someone who packaged up the implementation with a friendly GUI was making thousands a month on Patreon, while none of that was going to the people who actually implemented the hard technical parts.
Credit for these technologies can seem similar - the government does all the basic research (through universities etc), funds the development of the tech through grants and the like, and Silicon Valley just does the customer-facing part and picks up all the credit.
Nobody -- public, private, international -- has had any luck in fusion. I think that has more to do with the problem itself.
But consider "world-changing" technologies like electric cars. The SV model doesn't see so terrible, does it?
(Yes, I know about government grants. It's still a primarily private industry play.)
