Nobody forces people to buy macs, very few do, and as for iPhones, there are alternatives and apple doesn’t have a monopoly over the phone industry.
You can very well use icloud on other OSes too.
The shit they get to pull with safari is beyond IE level - they straight up don't allow alternative browsers (beyond WebKit) on 50% of mobile market.
nobody forces people to use windows either, but yet a company having 60% of the global phone market is pretty comparable considering that's literally probably more phones than people actively using windows daily
They should definitely open up iOS to installing apps outside the app store, but their position isn’t nearly as abusive as Microsoft’s. Even their 50-60% share of the mobile market is pretty competitive compared to Windows.
The second should be Apple for the same reasons.
Then Amazon.
