Of course you can criticise it and of course people can have their own opinions. And like in most cases, the majority of people doesn't care all that much to really have or even state their opinion.
Concerning the luck factor I always say: Everthing is a game of chance, if everyone involved plays perfectly or there is a small sample size. Be it poker, aoe, monopoly, tennis, or football. It is pretty easy to play perfect in some games (e.g. monopoly) and a lot of games are hard to get to a big enough sample size with to fight variance. Poker is not like that. Especially online, where you can play thousands of hands a day vs a lot of people who play far from perfect. With proper skill and bank roll management, it is pretty much impossible to go broke.
As far as addiction goes, I think there is a lot of stuff that is addictive. Starting with playing or watching any video games to watching TV, drinking alcohol, smoking cigarettes, doing drugs. Everything is on a scale in how severe it is, how severe the consequences are etc. What is acceptable to allow or to advertise is subjective. It changes from region to region and over time. So to come back to your first point, you can criticise it, you can try and go into politics, but you can't really stop people from not agreeing with you.
