Mostly burnout! Getting Antonia to where I wanted her took too much energy, especially with the tools available to me at the time, which were extremely frustrating to work with. Also I had neglected my other projects for too long, and those took priority. So essentially I finished her up and quit.

I can't speak for anyone else, obviously. I think there was an expectation that Antonia would at least get some uptake and support from the wider community, and when that didn't happen even after RDNA featured here...
