Assuming such an organization existed, what would stop someone from using their name, logo, etc. to also promote enhancing IP law and undermine they’re entire message? Presumably they wouldn’t be so hypocritical as to sue you for that, would they?

If IP stops being a thing, we can always invent new laws to replace it such as "impersonation".

Trademark and copywright aren't quite the samee things. We can get rid of copywright while still allowing trademarks.

Even besides you mixing up trademarks and copyrights, subverting the existing system in order to achive the opposite is not inherently hypocritical. E.g., the GPL is a copyright license.

Most anarchocommunists are against IP, so the wobblies (IWW) are a good shout.

Wait a few more months... let's see what the bittorrent and private crypto folks end up doing with AI... Either way, IP is going to either accept defeat or get very very loose in its claims, as the ability is almost here to just process a feature-length film, slightly modify each scene and replace script, camera angles, environments and actors with generic IP-free amalgamations, all while still capturing the tone and story... Images/text/code are already done for. Who's going to enforce that, and how much similarity do you need to infringe? Who's going to prove you processed that film when nothing about your movie is quite the same?
