So here we have the good guys using the law and ... at least temporarily ... winning... so what's your point?
I remember Rowan Atkinson (the UK actor) made a speech about this effect a couple of years ago and never heard about it since but definitely feeling it more and more... No exposure, no money, no legal representation. And at the same time we are being gaslit about our privilege.
It took 2 years because FFmpeg waited 2 years to send a DMCA notice to Github, not because of delays in the legal system. I think you are conflating different unrelated issues here.
