> I don't think counter notices apply to circumvention devices.
Right, because the DMCA takedown notice procedure as a whole doesn't apply to circumvention devices, only to content that is itself copyright infringement.
Why isn't this higher up? This seems like the actual meat of the discussion: Google is erroneously interpreting this takedown request as something it's supposed to comply with, when in fact it's not. Furthermore by misinterpreting requirements here Google is harming the public and newpipe. I wonder what newpipe's appeal (to Google) process looks like...
Putting on my conspiracy theory hat, but I've used the NewPipe android app for at least a couple years now and the experience has been so good I wondered why Google hadn't made more of an effort to quash it. Maybe this is a way for them to harm the project without looking anticompetitive or something.
