It's the fault of copyright. Restricting what shows you can stream to your users instead of, for example, being required to pay a royalty, inevitably leads to this situation. Netflix being the sole company allowed to stream every show and film would result in a monopoly that would be bad for everyone as they progressively sought to increase profits year over year. One company having all that power would not be a good thing for anyone, including content holders.
The solution is simple: every streaming service should be allowed to stream every show/film in every country. Then, piracy can only compete on price. That requires significant copyright reform, however, and is very unlikely to happen.
The guy in the video actually talked about how FL Studio isn't on Linux, and that's how he makes his living. He then goes on to say he has spent thousands of dollars on plugins and samples that only work on Windows. He then talks about how Asperite doesn't work very well on Wayland compared to Windows. The first segment was about how not all mods work on Linux. The last segment was about how Foobar2000 doesn't work on Linux and even through Wine some of the features are broken, and there's no true replacement for it but "if you're not as fussy as me, any of these native Linux software are great".
He also runs Debian 12 on his laptop part-time and seems quite knowledgeable about how Linux works, and is willing to invest the time.
He makes a point about he "wants to make things better, not sacrifice things".
