So, rather than fix a real problem, people start complaining about something a lot smaller: "18% of the world's phones run in a walled garden with a relatively modern browser."
Also, Linux works fine for plenty of people, sure miniscule in proportion, but it hasn't failed.
When you have 90% market share, you have a monopoly. It hinders innovation.

Sure, Apple has made Microsoft a little better but the monopoly that Microsoft has really means that they don't need to compete.

Apple's mobile market share in the US: 43.5% Samsung: 28.7% LG: 8.2% Motorola: 5.1% HTC: 3.8%
It always makes me laugh when people still, in 2015, try to pretend that Apple isn't dominant and getting more dominant with time, in the mobile space.
