What gave Stars the opportunity is that other providers had done the same ahead of time. Plus the move towards getting depositors to gamble in other games. It's logical in a sense - at some point you turn your attention to the ~33% share the winning players are taking from deposits and competing more against us for that share of $$.
Plus the move (by Amaya) to try and pay down debt/make their numbers look good by doing every short-term thing possible, probably hurting their long-run ecosystems a bit. It was a shady outfit that (somehow) borrowed $4 billion to (over) pay for a plateau'd asset. Their plan appears to have been to cut-and-flip after a few years, and it hasn't worked out so well in that regard. (Other than the cutting
)
Hopefully more sites like Global keep popping up, b/c having 5-6 niche ecosystems to choose from and move between is what's going to keep a grind nicely profitable for years to come. (Just not for the old "big money")
Then there's all the GTO/AI/3rd party tools that will keep getting better at the top levels (and leach-down some to lower levels as well). Us old folk have to stay nimble, stick-and-move, etc...
