The purpose of faucet is marketing
just anyone sit down and do calculations: how much does someone earn with facucet? the person earns little and is earning in a casino and taking the same money to play in the casino, the casino is not earning any profit with that, I don't even know why casinos do such a thing, because they don't make a profit with that kind of thing, the only something that gives them a profit and when people make deposits at the casino and lose everything, then the casino makes a profit, but if people deposit and win a lot the casino loses, there are people who make large deposits and when they win the casino loses a lot of money
Probably he's referring to market people to come into the platform, this has been a thing in the past I'd say when people are getting enough on their faucets but right now, it's too rare people will get into that unless worth it for them. There are too many different types of marketing and giving faucet to try to especially for newbies means a lot for them to try it out, just my two cents. By the way, I started to be lured into faucets way back then.
