Joanito I'm pretty sure they didn't ban providers because the games aren't paying. There are different volatility's and different RTP.s. All of thease games have a common feature though, they are programmed to make money to providers not the players. So you can only excpect to lose in long term gambling.
But I personally think that it is fair that those providers who co-operate with Casinodaddy gets more streamtime. But that might not give enough pressure to the others companies because there is many other streamers who still plays their slots. So maybe the provider ban is not the best solution and instead of punishment to the other providers it would be better to give thease "co-operatin" providers some bigger attention. Maybe more advertising in the stream and aboutslots website.
But never the less we still have what we like most in this stream, many interesting personalities that are all very unique compared to each other. So the stream will be still entertaining even streaming only one slot all day. I guess there is no right or wrong solutions to these kind of problems and only way to figure out is to try something new and learn from it
