It's crazy isn't it? This community thinks Apple and Google are monopolies despite being competitors, ditto Twitter and Facebook. Microsoft isn't though. Not because they don't completely own the Desktop PC market just as they ever did, but because that market is less relevant than it used to be for web devs. I live in a strange time.
You live in a town with no fresh water, and the only drinks available are sold by the local store. This store does not sell bottled water, wine, orange juice, milk, or tea. The only drinks it sells are Coca-Cola and Pepsi. But if you don't like Coca-Cola, just buy Pepsi - how silly it would be to complain of monopoly when you still have a choice!
The store? Then your analogy is flawed because there are other big stores that sell basically the same stuff and even some small shops. Not a monopoly. If all of them choose not to sell that product that doesn't mean anything. They don't have any obligation to carry whatever you want.
Man, people are being absurd about this whole thing.
