You should give them a friendly reminder that removal or alteration of, or false provision of, copyright management information, is a separate offense under the DMCA that they can be liable for.<p>(IE you could commit no copyright infringement, and still be liable for removing/altering/falsifying the CMI).<p>see <a href="https://www.law.cornell.edu/uscode/text/17/1202" rel="nofollow">https://www.law.cornell.edu/uscode/text/17/1202</a> and

Wow these guys are ungrateful idiots.<p>Managing to violate MIT is pretty special in its own right but instead of acknowledging the author, or thanking them for their work and promising to comply with the license, they threaten the guy?!<p>Is there a good way to crowdsource a legal ass-kicking?
