Microsoft, since at least Windows XP (and perhaps before, I'm too lazy to look), hasn't shipped a programming language with their operating system. Apple ships what, 6 or 7? Python, Ruby, Perl, C, AppleScript, and probably a few others. Those don't require the $99 developer license at all. Apple is the only hacker-friendly PC and OS manufacturer remaining.
Every Linux distribution includes dozens of programming languages.
For developer tools, VS Express has been free for over 5 years.
