> Visual Studio is not on anything but Microsoft platforms

That's a specific piece of software. You can write programs for Windows, Windows Phone, Linux, Android, and even OS X in Linux, but not iOS. Jetbrains have a suite of IDEs for developing applications, but the iOS one had to be gimped to only work properly on OSX.

Yes, well it turns out that Apple lied, and you can in fact watch the stream on non-Apple hardware.

The issue I am talking about is much deeper than this - this is just one issue. It's also about, for instance, how every time someone at Apple talks about other company's products they seem to say incredibly derisive and needlessly aggressive things about them.
