I would wager a guess and say that many joined long before they got this bad, probably because back then their visions and values were a lot more aligned
Nowadays I rarely see more than hectic startups and Big Tech, both of which have massive downsides which affect people outside of their field too.
Additionally, especially at the HQs of Google and others, many SWEs live in vans on the street because rent is too high, they cannot just work somewhere else as that won’t actually change the situation
