In fact, Apple charges more, so it makes it even more difficult to buy them than an Android phone -- which also has multiple app install options. Why not use that?
> If some big app owner like Facebook or AirBnb came out and said "We're only supporting Android now, so please switch phones to use our service" they'd just go out of business. That's the essence of monopolism.
I think that's just called bad decision making, which vendors are completely free to make. There are plenty of apps that are Android only, and I'm sure they fully realize their revenue will be less as a result. There are also plenty of third party game developers making exclusive titles for Playstation or Xbox all the time. They're roughly neck and neck outside of Japan, but in Japan, it's no contest, Playstation is completely dominant. Assuming we ignore Nintendo, would you then suggest that Sony has a monopoly on consoles there? One could claim that if you're a developer in Japan and you don't target Playstation in Japan, you're going to lose. But if the goal is maximum revenue ...that's just bad decision making. If the Xbox market in Japan just isn't coughing up dollars, how is that Sony's problem?
Rather than continuously trying to compare Apple to a monopoly, which it isn't, I think the more effective comparison would be with RAND and FRAND. I don't know what kind of legal hoops would need to be jumped through to make the legal justification work, but it seems like Apple has an essential technology (the App Store), and must be obligated to license it (arguably reflected via the fee it charges), but that is an extant example of government regulation where the fee could be legally managed.
Now, don't get me wrong, as a consumer I do want to _own_ my device and have the freedom to do anything with it, even if I never exercise that freedom. And as a consumer I use my right to vote with my wallet by never purchasing iPhones and explain my decision to anyone that cares to listen. But in no way does that mean that I think what Apple is doing is wrong or illegal nor do I think they should be forced to change their business model because some people think they can have the cake and eat it too.
So I am forced to use an iPhone. Regulation is necessary in Oligopolys.
You can, on the other hand, support businesses or communities that are.
