Really? I found that I only really look at the code when I look at projects I'm involved in. Usually though I use GitHub for discovery and then I care much more about the languages, commits, releases and Readme.
I pay them money on several accounts, maybe it's not enough and IBM asked them to do this? I'm not sure how well MS and IBM get along, IBM saw them as public enemy #1 when I left, but where paying for GitHub?
