Now that Microsoft has been open sourcing so much stuff I was expecting Apple to follow the wave and release Swift as open source too. It's a shame though.

Let's not forget that webkit when it was released was little more then a code dump - one big patch that had to be applied to KHTML.
What Fortune 500 (or even 5000) systematically open sources every piece of technology? Every company I can think of -- Yahoo, Microsoft, Google, Facebook, LinkedIn, Twitter, Amazon, LinkedIn, AOL, Craigslist, Oracle, -- selectively decides what to open source.
I'm not saying that's right or wrong, but Apple is far from alone in doing so.
