I didn't speak my mind immediately, for reasons mentioned above. These days I am slightly more vocal since I have less to lose, but I think the biggest damage has been done, the culture significantly shifted for the worse and it's a direct result of a "let's bring in adult supervision" decision.
Thanks for your other point, but this is the last startup I work at for a while, next one is going to be a big and stable company (hopefully a FAANG), with perhaps more politics but 1) more talent on average 2) more predictable financial outcome (being stuck in "maybe golden" handcuffs not knowing if it will all be worthless in the end really sucks).
