Just because you love walled garden, doesn't mean others think the same. In fact you are the minority. This is especially visible on Android, where Google introduced side loading since the beginning and is struggling how to disable it. For example by blocking it in new android based products like Android TV. Or EU ruling that Apple needs to provide side loading, so Apple still only enables it on EU SIMs, making it hard to still build products with it. You mentioning Windows that it's "a privacy and security a clown show". Yet you are dismissing that Linux is for servers. That still doesn't change the fact that Linux is even desktop is much more secure though. Also mobile problems was not solved by mobile phones, in fact it was much worse, and more recent windows versions "backported" those ideas. > It wasn't conceived, for example, to stop car manufacturers from engineering the cars to accept parts that are only made for their cars. That's not what antitrust law supposed to protect. It's clear that different products will have different parts, what antitrust laws would do (if they weren't rendered toothless) would punish any blocking of competitors springing up.
