It's not clear that the RIAA needed to spend any real lawyer man hours making the request, I don't think a designated agent needs to be a lawyer but even if they do they just send a form letter.
Welcome to the future. Github has received “a DMCA” from the RIAA’s film counterpart requesting they take down another repo for tool that does not contain proprietary copyrighted material (this time not even including a test suite that downloads it IIUC), and apparently instantaneously complied. As of the time I’m posting this, it’s been more than a day (an order of magnitude longer than “a couple of lawyer man hours”, times 1–2?) since it was posted here https://news.ycombinator.com/item?id=25836503 and I’m still not aware of any other response from them so far.
It's also something that requires lawyers/law staff, not just random people, for maximum effect.
But yes, this is definitely a positive thing! I'm not sure anyone but the EFF would have done it succesfully, I am grateful to the EFF... and, yes, to github for their response, which not every company would have had.
The RIAA got effortlessly blocked here with a couple of lawyer man hours, which contained information gathered from a handful of really interesting blog posts.
I would say this entire story is something to celebrate, because it shows how easily a single person could stop this.
Mitchell L. Stoltz, Senior Staff Attorney at the EFF signed this letter, which probably took no more than handful of man hours to compile.
Pretty great roi.
