Samsung and LG make high-end phones, and there are plenty of good personal computer vendors. And Windows is certainly a desktop OS that some people choose.
Apple doesn't offer any services unique to itself. It does offer a slick-looking and well-marketed "ecosystem" which is really just a bunch of different things that you could get from other vendors.
The only way out is either regulation or a whole paradigm shift that renders phones irrelevant. I'm not sure the latter will happen any time soon.
So I 100% agree, we need more competition. I was hopeful for a fleeting moment in time with the Firefox phone.
