It's also ignoring the fact that much plagiarized code is already under permissive licenses. If Star Wars or Daft Punk were CC-BY-SA nobody would need to pirate them, and there may even be a vibrant remix culture... which is kind of the whole point of open source, is it not?
I can only imagine how frustrating it is for the average user when they click on an "unhydrated" button that does nothing. JS frameworks embracing SSR is definitely a step in the right direction compared to the fully client-side apps of the previous hype cycle, and yet in many cases can still present worse UX than PHP sites of yore.
