That isn't a counter claim, it is a lawsuit by a company that isn't affiliated with youtube-dl and the claims of the suit predate the youtube-dl incident.
In 2019, the RIAA got a court order to have Google remove the Yout domains from search results. Yout is arguing that their service provides time shifting, which is fair use, and their domains should be restored on Google search. Plus, they want damages.
FYI -- Yout has been blocked from several ISPs in Europe because courts have found their service to be illegal stream ripping and infringes copyright.
Are you hard of hearing? The link you posted has the filing clearly visible in the video. I read it. All claims are based on actions taken in 2019. Not one mention of the youtube-dl DMCA violation.
