Why did microsoft get sued and why isn't anyone suing apple?

I'm tempted to say that's wrong. [/color]

It's right.

The evidence gathered during the investigation leads the Commission to believe that the tying of Internet Explorer with Windows, which makes Internet Explorer available on 90% of the world's PCs, distorts competition on the merits between competing web browsers insofar as it provides Internet Explorer with an artificial distribution advantage which other web browsers are unable to match.

Whereas Apple does not, at all, allow developers to use any programming language apart from C and JS. This includes conversion from, say, Python to C, or Clojure to C, or Flash. You're strictly speaking not even allowed to make pseudocode of the app you're making, nor allowing to simulate anything. That's why flash is not allowed (You cannot make a turing-complete thing. You're not allowed to make the Game of Life. Heh.).

But keep in mind, Apple has never shutted anyone out: They're actually doing the opposite with their Appstore.

What you're bothered about is that it is legal for Apple to write in their TOS that:

3.3.1 Applications may only use Documented APIs in the manner prescribed by Apple and must not use or call any private APIs. Applications must be originally written in Objective-C, C, C++, or JavaScript as executed by the iPhone OS WebKit engine, and only code written in C, C++, and Objective-C may compile and directly link against the Documented APIs (e.g., Applications that link to Documented APIs through an intermediary translation or compatibility layer or tool are prohibited).

It's stupid though, imo.
