Hmm, correct me if I'm wrong, but isn't monopoly law (at least in EU) dependant on the companies market power (e.g. the ability to sway market / damage consumer rights), not market share?
I imagine so, but it's hard to be in a position like that when you have less than 20% of the market.
But Apple had 90% of profits, isnt that a better metric of monopoly?
Monopolies are interesting because they limit choice. Increased profit may be a side effect, but that's it. It's accidental, not essential, to the definition.
