This may suprise people, but the counter guys/girls in Ladbrokes also get paid !
And people with adverts on there YouTube videos get paid, and the BBC with there licensing fees get paid, the people who serve you in maccies get paid.
Personally i believe if you gamble with in your means and keep it fun there’s no issue, it’s just some people want to blame someone for them going out of control, they have the options of deposit limits etc, if you chose to gamble why are you against someone advertising it, you’d do it either way
