I mean yes they are getting paid to play at certain places and that is why they get money from the casino and that means that we are talking about free entry type of deal for them.
However, they could also gamble with that money without competition and still lose that money if they have a bad luck. It means they are gambling just like any other person. Their income is not the money they are given by the casino, their income is mainly what they make from streaming. This means they could be considered gambling just all of us, we find the money from other places, whereas they find it from casino itself, however afterwards is all equal.
However if they are getting money from the sponsorship and then they are using it back and losing it all, they are sort of different from the regular person who gambles with their own money isn't it? I mean think about it, they are losing absolutely nothing at all, getting subscription income, getting maybe more sponsorship on other stuff, and they are getting donations and now on top of that they are allowed to join the competitions and win something from that as well? That should not be acceptable and that is why I understand why people do not want them to be getting accepted on the competitions.
Maybe the smart way would be to pay them regular money and to their bank account or crypto wallet, then they could do whatever they want with it. If you are putting money into their casino account then it is not really the same as me playing here.
