One of the many suggestions from other merchants that I found intriguing was to attend the next Linden Lab Commerce Team office hours in silent protest. You eat popcorn instead. The idea is that Teh Lab is not going to do anything based on what you say and you're screwed anyway so just register your displeasure.
For those that want to take this approach, I put together a little kit:
Protest Popcorn with a munching gesture (also full perms but only partially made by me). There's also a nice notecard with some thoughts, ideas and other crap in it.
