If I understand this correctly, few people are playing poker these days and it's becoming harder to find pokers players to play with?
So as a result, the companies you listed are providing the poker players themselves?
not few but way less that what it used to be before Black Friday
before Black Friday people could play poker pretty much anywhere in the world without getting problems , so it was easy for people who just want to have fun to create an account and deposit
after BF there were many restrictions also people kinda started to be scared of that happening again so the majority of fun players just stopped playing
now it's way harder to profit of poker due to lack of available sites and due the fact that the majority of the players these days at least have decent info about the game and how to play it
