Well, you have to keep in mind a few things here. Firstly, not everyone agrees that adult content/porn or gambling is 'immoral', and in many places that attitude is a fair bit relaxed than it is in the US. If you don't see it as 'immoral', then frankly, working for a company in such a market is no different to working for anyone else. Then in many cases there are the job perks offered. For instance, while these types of companies won't outspend Google or Facebook in terms of developer salaries, I have heard their wages are pretty high for the markets they're hiring in, and they apparently do offer things like events and more relaxed working environments than other companies. In other words, the same way finance firms often get good tech people working for them.
