Great, most major ISPs now block all torrent, file-sharing and kodi sites because rightsholders paid them to.

Actually it’s because they’re afraid of being sued by rights holders, the rights holders have only “paid” them in the sense of “We’ll not file this extremely expensive to defend yourself in court case against you if you add these anti-piracy countermeasures.”

Which is entirely OK if I’m reading the EFF’s argument correctly because it’s, while not exactly the same as a court order, is basically an out-of-court settlement that amounts to the same thing.

Some ISPs are also blocking sites talking about abortion and LGBTQ issues because of pressure from certain states.

Yes, and if you follow the EFF’s logic, that’s also entirely legitimate because the government should decide, not ISPs, what’s allowed.

You’re not illustrating how this is a slippery slope (which is a fallacy anyway), you’re illustrating just how insane this EFF position is.
