They... didn't? They got a petition response from the EU that was more positive than they had expected, and a response from the commission is not court: the response phrasing literally leaves the door open.

Heck, the parallel movement in the US even had a major legislative victory in California, so... what are we talking about?

They’re still around so I don’t see why having a legal setback is the same thing as going poorly. They are attempting their mission again with new bills in US and EU.
