But none of those things are a monopoly. A GE oven that only cooks GE food isn’t a monopoly, it’s just a shitty oven.

Plus, monopolies aren’t illegal, using them anti-competitively is. So the analogy would be GE buying or putting out of business all the other oven makers, then saying you can only cook GE food in a GE oven.

It's maybe not a monopoly, but it's definitely tying, which is still covered under anti-trust law.
