That's not really a self-contradiction; if we pretend the USA's copyright lobby had made California pass a similar law… well, that might not work, I have no idea if that would be unconstitutional inter-state trade restriction or something in the USA, but for the sake of showing why it's not a self-contradiction can we pretend?

If the US media elites had convinced California to do that, they'd be a "shadowy cabal of [US] media elites", even if there was opposition from the rest of the USA.

Again, don't read too much into if this would actually work in the USA, the EU is not the USA, this isn't that kind of comment.

It's not that long ago that US media conglomerates used MPAA to threaten Sweden to remove piratebay?

US media elites got DMCA and YouTubes copyright strike introduced, I suppose they were powerful enough to sidestep the states and go after Congress instead.
