Are you just figuring out they're a casino? Their main thread is in the gambling section and this thread's title mentions the daily jackpot and wagering contest. Of course they're a casino, they're not a charity. The faucet and other giveaways have to be sustained somehow and if you aren't a gambler, lottery ticket buyer, and you never deposited then there is no reason to expect they will give you bonuses for nothing in return.
I guess some people think it all comes from a magic Bitcoin tree. The people who gamble their own money pay for all the free users so they obviously deserve to earn the bonuses.
