Although I agree with you that this strategy might work in a duopoly type situation, where there are two platforms competing against each other, in a borderline zero sum game. The problem, though, is in markets where there are more than two participants. What happens when Mixer does this strategy, as well as Facebook gaming, as well as youtube gaming? Answer: the costs shoot up into the stratephere, and all of them go bankrupt. It is kind of like a game of chicken. Massively overbidding to buy out the entire market only works if there aren't other people out there who are willing to meet you at the same level of irrationality, and burn the whole thing to the ground, along with you. IMO, the only real workable strategy, similar to this, would be if those are smaller platforms, agree to do some sort of team up (which is sorta what is happening with FB gaming and mixer), so that the irrational actors don't all lose the game of chicken.
