Back when I was working with HP-UX, GCC worked if you wanted something completely independent and didn't need to link against system libraries. For the companies I worked for when using AIX, that wasn't an option.
At least on AIX and other UNIXes, the system compiler and GCC worked together. HP-UX was a special kind of hell.
A sibling reply pointed out that developer kits and distribution deals for consoles (which are general purpose computers, regardless of how they are presented, as much as modern smartphones are) are extremely expensive (and there are no alternatives for distribution).
The point that I am making is that the idea that you can develop and distribute for free on any platform is a relatively new one.
It is not new on microcomputers, though, and those have essentially defined the expectations for consumer devices going forward. That is why it was such a big deal back when Apple first introduced the app store with all the restrictions - that was new, even compared to other mobile devices in the market (even feature phones had J2ME by then).
But regardless, it seems like a good idea in general, and proven to work, so why shouldn't we want more of it? I don't see the problem with applying the same logic to game consoles etc - that racket also needs to go down.
