It appears to be a bonfire of vanities on all sides. One side goes "I use the trust you invested in me to block you from project resources, because my other project is soo much better but has less name-recognition." The other side goes "We are more pure, more righteous, and more petty at the same time! Let's show the other side by registering a confusing domain name and release a similiar but still different software with a long blurb why the other side is bad and must be destroyed! Oh yeah, and let's write scathing e-mails so nobody misses that we are petty."
This seems so weird to me. Why invest the energy? In the olden days we'd just fork and get to work.
