It's not like larger companies don't also screw over their employees in various ways. After having to leave AWS due to my fully distributed team that was formed during WFH being forced to "return" to an office that most of ever never lived near, I've preferred working for smaller companies not because I care about equity (I'm in the fortunate position that I can survive comfortably and save for retirement on my salary rather than needing to rely on the value from options/RSUs), but because my confidence in my ability to predict where things are headed goes down increasingly with each additional level of management between me and whoever has the power to arbitrarily decide to upend my employment on a whim. In the long run, I'll probably be fine if my employer doesn't make me rich, so as long as my projected retirement age isn't actively getting pushed back based on my current income and spending, I'd rather optimize for minimizing the likelihood I suddenly find myself unemployed due to untenable working conditions or getting unexpectedly laid off. My experience at startups has been that it's a lot easier to tell when things might start to get dicey several months down the line and start to prepare for if I need to find another gig. With a large company, I've seen that happen much more suddenly for people who had no reason to suspect they might need to in advance.
