even more pronounced when you look at web software. look at the most watched projects on Github and play spot the GPL license: https://github.com/popular/watched I couldn't count a single project. I have never used the GPL in any software I write because I want anybody to be able to use my software and contributions. Google, Microsoft, Apple (who are actively purging what remains of GPL code) et al will not adapt you…
I can only conclude that the number of Github users "watching" a particular repository is not a particularly useful metric for how good/important/popular that software is.
Finally, for obvious reasons, Github has a pronounced Ruby/Rails bias, and that community already has settled norms on licensing.
