You post the same data now with article that doesn't even have word "steam" in it. Your various sources weren't linked. I think that clears why your source is "nonsense".
Yes my words are changed because, you somehow read me saying multiple times of steam being monopoly in single use of phrase, steam behaves like a monopoly. I repeat, not liking one store doesn't make me a fan of another, they both are horrible.
As for examples of anti-competitive behaviour, price matching that is being discussed in comments here is a big one, don't you think?
The dumb part is it takes place 200+ years after "the bombs fell". You can look at how supermarkets fare after 5-10 years being abandoned, there won't be anything after 200.
