Like another commenter said, many people are willing to put up with a lot just to work in games, even in a low prestige role. Also the bar for support/QA jobs in pay and treatment is very low across pretty much every industry, so paying a decent wage and offering good benefits (plus annual vacation to Hawaii) is a big plus. That said, it’s still not great - the “flat” structure leads to a lot of really toxic power dynamics where those roles always end up at the bottom with no real agency or recognition.
