Not everyone who could easily change jobs realizes it, especially after being worked out on awhile by a workplace culture that seems to prioritize gaslighting good engineers into thinking they're poor ones - cf. Fowler, and imagine how much worse it is for someone less confident in herself.
Not everyone who realizes they could change jobs does so, and not because they like the shitty culture where they are - Uber uses golden handcuffs, too, and that's not an Uber problem, but a startup culture problem in general.
Abusive relationships tend to end when the victim gets a "wake-up call" - a moment that takes them outside the narrow perspective their abuser has been at such pains to create, and brings home the reality of their situation. There are certainly people at Uber for whom Fowler's article, and the follow-on exposés it's prompted, have constituted just such a moment. And now that they're trying to get away from their abuser, they get to deal with being stereotyped this way? That's trivialization.
