Would you say the same if the car market suddenly coalesced into a duopoly and the car companies become very restrictive? Would you defend only them being allowed to do basic repairs in the interest of safety? One going as far as saying you need to buy their tires or tires from companies that pay them tribute or the car won't start, their seat covers unless you manage disable some weird detection, etc The other allowing such stuff just making it a pain. Would you then say a company just needs to pop up and meet this demand? Despite all the stuff involved and the size of cars would be a lot lot easier. Because at least cars don't necessarily need an ecosystem, userbase and developer community outside of the company to get of the ground and get sales.

As soon as you apply these things the other industries they start sounding ridiculous and hilariously anticompetitive but with phones people for some reason have come to accept it.
