GTO poker is 0EV for players with equal skill and strategies.
Exploitative poker uses deviation from GTO to gain an edge over a strategy, but in itself can be exploited.
ABC poker is an understanding of fundamental strategies, and finding what works best for your style/temperament.
Everyone implements some form of all three at some point of their play, whether it's unconsciously, or calculated.
And for that reason, players are flocking back to poker. For a game that would take several lifetimes to solve, technology has begun shrinking that time to near human expectancy.
But what most don't understand, is that one would have to commit a lifetime to purely studying the game, and nothing else.
Most don't have the will, or ability to do such a thing, and think that it's some new way to make money quick.
GTO is an old concept, that is just regaining new life.
Look at the Fundamental Theory of Poker, it's GTO in a nutshell.
I can't disagree with "poker is not a collect comination game" part of your message.
But I do disagree with poker being unsolved game.
Objectively poker is a solved game for long time. It's obvious that one participant in the game is always in profit. It's the dealer who earns rake. Rake is a small, but stable profit that turns into huge profit in a period of time. So the dealer, or poker room is a constant winner, while rest of the participants are just rake generating schimpanzees. And dealers main job, I mean his main focus is to keep apes playing the game as long as possible, that's why they're paying soccer, ufc stars, singers, actors, brokers to play the game, because these people have fans and some part of these fans will blindly follow interests of their admired star.
Poker is about money, not about cards,
odds, flushes and pairs, not about human behavior types. This game is only about the money. There is no difference for a pc server when it hosts a 1000 player freeroll or when it hosts 1000 player $1.1 buy-in MTT or when it hosts $109 Sunday million MTT. In all cases computer will consume less than one dollar of energy and traffic. The profit of poker provider is based on greed and on visible chance to win a big prize.
If you're still not getting it - try not to split poker players into sharks and donks, DO not split players into "often winning Regs-Pros" and "always losing newbs"... Try to split poker world in 2 different parts: 1)Poker consumers(community) vs 2)Poker providers(
poker sites and
casinos) and it will be obvious that one side always wins, other side always loses. This is why poker is a solved game, and the winning part will give you more and more reasons to play the game, like new concepts, huge bonuses, new types of poker and so on... But objectively it's not different from trading mirrors to gold bars. :tomato

oker teaches you nothing good, no new knowledge, just some easy school-like calculations and stereotype-template thinking. Majority of poker "regs" could earn much more money having some real job and doing something useful for the society than trying to rob the one who tries to rob you at the poker table.
P.S. Sorry for the language that might sound little bit rude.:icon_flow
