No need to remove it. Just disclose it to the users. It is supposedly a great plugin (as per rating on the chrome store), and you deserve to be compensated for it. Just let people know at the time of installation how this plugin is expected to trickle some money for your efforts, and you should be fine.
My initial reaction to this was shock and disgust and I quickly uninstalled the extension.
However after seeing Joel's actions to address the issue promptly I'm glad to re-install the newest version.
I think, like many users, I really don't (didn't?) mind as long as the details of what's going on behind the scenes in the extension are clearly explained. I would even be happy to pitch in a few affiliate shekels with the developer of the app.
