What happened to the "software patents are ridiculous and should never be granted" argument? Now it seems that the same sort of people advancing the anti-patent argument are angry about FB's licence. This seems like pretty muddled thinking.
Now, it appears there are many people thinking they will at some point get filthy rich with their patents. And I've frequently seen the GPL being derided as some sort of communist plot.
It's good to see that at least the large companies are still on the side of openness, although I fear what will happen when today's commentators become tomorrow's CEOs. Imagine something like the nodejs ecosystem, except now you'll have to buy a $1000/year subscription to the "node modules starter edition".
