I wonder how much involvement there was from Microsoft on this matter. Either way, good job guys!
Microsoft is a member of RIAA.
And also the owner of Github.
"The RIAA reports that total retail value of recordings sold by their members was $10.4 billion at the end of 2007, a decline from $14.6 billion in 1999"
Not sure where that value's gone in the last 13 years, but it didn't look like exponential growth.
