I'm not surprised. If you grow up as a computer nerd all your life with few recognizable achievements, and suddenly a Big Tech company dangles in front of you $100k or more, very few people can say no, especially if you also grew up from a relatively poor background.
I think it's actually something unique about Americans. When I started my company, I wanted our slogan to be "Helping each other, together". I very quickly realized that no one in the US actually responds to a saying like that. The vast majority simply doesn't "get" it.
Sadly it makes it harder to find a job as a software engineer in which I can work for a company or in a position making a positive impact on the world (as amorphous as that may sound).
Any interaction that I've had with a recruiter when considering looking.
Me: "I'm not interested in working on ad tech or a bank, etc. I'm interested in privacy companies, green technology, conservation, etc."
Recruiter: "I have a job with Investment Bank X that I think may be interested in."
