Do they have an obligation to export your data in a format you choose with a method of your choice or can they make that determination for themselves? Does the EU mandate the ability for YouTube-dl to exist?

There’s a lot of talking past each other going on in this thread. Nobody is defending the RIAA or DMCA. But they exist and this outcome seems painfully obvious.

RIAA being mean, DMCA being bad and copyright being outdated doesn’t matter here. What matters in that the law exists and YouTube-dl made it really easy for the RIAA to make a compelling case against them.
