So, are they going to also issue a takedown for YouTube Premium next? Premium allows you to watch/listen without ads and also allows you to download videos for offline use. If I pay for YouTube Premium, there should be no problem with me using youtube-dl to timeshift the content I've already paid for. It's no different than using a DVR to record a show off a cable channel I pay to subscribe to.
Really, the RIAA should be going after YouTube for better remuneration, rather than going after youtube-dl. Unless I'm missing something, they get paid no matter whether the view comes from a browser user-agent or youtube-dl user-agent. How is this any different than recording a song off the radio, which is, AFAIK, legal under fair use?
That is a pretty sweeping generalization to make. I've been sick with ME/CFS for several years now and I've never come across another patient dismissing psychological illness as not debilitating. Instead, many that I know have premorbid or comorbid psychological illness and know firsthand how debilitating psychological illness is.
If a person with OCD was told that their illness was due to poor lifestyle choices and that they could be cured of their OCD if they just stop believing they have OCD and that they just need to get to sleep on time and get a bit of exercise, they would probably not appreciate that. This is how people with ME/CFS are treated by many health professionals and medical researchers. There is a large and influential group of psychiatrists that posit that the disease is caused by nothing more than the belief that you have a disease. This is why there is seemingly an intense backlash against psychiatry and a frantic hunt for biomedical proof in ME/CFS.
