alt Hacker News> Neither MacOS nor iOS are anywhere near being dominant in their markets in the same way Microsoft was with Windows.
A market is the set of goods or services that are fungible substitutes for one another. If Ford and Chevy use the same kind of battery as each other but Honda and Toyota use a different kind then "battery for Ford or Chevy" is a market and "battery for Honda or Toyota" is a different market. If they each require different kinds of battery then "battery for Ford" is a separate market from "battery for Chevy", but even within those markets there can be multiple competitors, i.e. Ford isn't necessarily the only company that makes batteries compatible with Ford vehicles.
Whereas if Ford vehicles use a different kind of battery than other vehicles and there is only one company who makes that kind of battery, "battery for Ford vehicles" would be a market in which that supplier has a monopoly, regardless of whether the one supplier is Ford or someone else.
Which one of these looks like what Apple is doing?
> Ford isn't getting sued either for only selling cars with Ford motors inside.
Ford isn't only selling cars with Ford motors inside. They offer them that way, and it's a popular purchase option, but they'll also sell anyone essentially any part of the car by itself. They also don't prohibit you from taking the engine out of your Ford and putting it in a Chevy or vice versa.
This argument is always being made on HN and is always wrong. And it becomes more wrong every time it is repeated.
Because with that logic, every company in the world is a monopoly because every company in the world has their own niche and their own products which are different from others.

Ford would never sell you a car with an engine in it which isn't from them.

Apple doesn't prohibit you either from ripping out the motherboard from the chassis of whatever device and putting your own stuff in there. People change batteries etc.
