RIAA Abuses DMCA to Take Down Popular Tool for Downloading Online Videos
"DMCA 1201 says that it's illegal to bypass a digital lock in order to access or modify a copyrighted work."No, 1201 says, among other things, that it is a violation of the Copyright Act (which may only carry civil liability, so not necessarily "illegal") to share the means to circumvent access controls to a copyrighted work.  That is the part of 1201 the RIAA cited in its letter.It is the sharing that is the alleged 1201 violation.  Not any circumvention.
