I haven’t noticed a political association with copyright cases, I know some conservative Judges in Texas counties pretty much kicked copyright trolls out of the courtroom when they tried targeting defendants using IP addresses.

Intellectual Property also seems like a more liberal realm, Hollywood, Silicon Valley, RIAA, MPAA, Disney, Apple, etc. all seem to be quite left leaning.

They aren't. Like others have pointed out, RBG was a copyright maximalist and all the proponents of strengthening copyright, RIAA, Hollywood, Silicon Valley, etc tend to be left-leaning.

No idea where that line of thinking came from. Though if I were a little more cynical I'd say sometimes it feels like there's a trend to attribute everything negative to conservatives.
