The usual reason is #3. You're only willing to pay shit and instead of compensating for that with actually useful things, you're selling philosophy and crap like "company culture", as if a company that's not at least 15 years old can have that.

The reasons you listed are all nice, but most of the people who do it are doing it for reasons like #3 above. You risk ending up in the same pot as they do.
