It’s always easy to be an open source proponent when you are the underdog.
And Microsoft, as crazy as it sounds to me, kinda is when it comes to cool dev stuff.
We'll have to see if they have really changed or just waiting to regain ground and going back to the extinguish part.
But what I can confidently say is that, of all the BigCorps, Microsoft is the only one actively trying to make developer's life easier.
Apple is consumer first, so MacOS is getting harder and harder to hack on, for better and worse.
Chromebook was never a serious competitor. And Linux is Linux, hackable to a fault.
But Windows… which I have always despised, is, for the first time in my life, tantalizing… to some extent.
