The HN crowd here? A mixture of 'I told you so' posts, some fascists posting with glee that their perceived enemies are getting kicked in the knees and probably a few centrists desperately still trying to find a way to spin it in a positive manner.
The people running Y Combinator? They'll donate a few million to the Trump fund, maybe donate a jet or two and hope that gets him to stop for a little bit while claiming this 'isn't what we stand for' and 'i can't believe this happened (to us)'.
Make no mistake, they have no problem with these decisions until it has direct and material impact on them. That's why they invite the people directly responsible for this to their AI Startup school and give them privileged speaking opportunities. They don't care nor do they think that far into the future. Hell, you can go to the AI startup school page now and see them sharing the AI Ghibli shit [1]
The techbros aren't too worried. Elon, Peter Thiel and the Paypal mafia put Trump into the white house and have a direct line and special carvout exemptions. JD Vance was groomed by Thiel and is a heartbeat away from the presidency.
