Steam

While you may have a point that we can't know what any company will do in the future, the fact remains that Valve has earned their place by 2 factors alone:

1.- Constant innovation to make their platform a place where everyone wants to be, without crippling the competition, despite having the means to do it. 2.- years of building trust with their users and providers alike by being transparent and clear on what they offer, while adding value which costs money that they absorb.

Yes, 30% of so much money is a shitload of money, but I have yet to see one good reason why that's a bad thing other than the usual "it's too much" bullshit argument.

Unity, Reddit, Google, Apple, Microsoft, Amazon, these companies have 1 common denominator: they have gone out of their way to destroy anything that would present a risk to 10 cents of their revenue, including, but not limited to, absorbing any potential competition, regardless of if they represent a risk to their dominance or not.

Do not compare valve to these assholes. Valve is making tons of money? Unless you can show me, with evidence, how this is detrimental to anyone else, other than the fact that you are not making as much, all you have is bullshit and a fucking tantrum.
