If we just look at Linux, there is the push to hide more things from users not the other way around as more people use it.
Perhaps in the case of design mad developers like the GNOME team. But even on distros like Ubuntu, it's miles from Apple where any such capabilities are removed entirely.
That's why people dislike Ubuntu and power developers use Arch Linux.
And in the Apple world, there are no alternatives. No real options. All or nothing. Their way or the highway. Thankfully we have competition against them, but we just had a nice FUD article yesterday that said "OMG NEW ANDROID VIRUS" that no one can actually claim is in the wild and requires back flips to install.
And how many support cases would they get saying: "Well you let me install from another site other than the Apple store, what do you mean you don't support your product?" Try explaining to an end user the difference.
There is no evidence this would be the case yet you assume it would be a given!
