As I have read the responses on this mail list, several people have made some very good points, but others not so much. Some focus specifically on Eric and others are more broad commenting on cultural issues within the project itself. Eric said some bad words, most of us are adults here, so deal with it. Its really not that big of a deal nor is it worth all the effort being put into it. There are far worse problems in the project doing far more to bring it down than Eric and a few cusswords.
One point point for example by a couple folks indicated that Eric is responsible for running a lot of people off the project. Eric can be a jerk sometimes and use fowl language but I am not familiar with one editor who has stated they stopped editing because of him. I have met quite a lot that have stopped editing because of abuse by some admin. People are leaving, but Eric is not the biggest culprit, its the us and them mentality of some of the admins and their being exempt from the rules. So if folks are concerned about people leaving the project, I would suggest they start there.
Some have also suggested some issues with the Arbcom. Sarah Stierch questions its legality (as do I and others) and some have indicated they intend to go around the Arbcom and appeal its verdicts. To this I say good luck. I really wish they would, and its high time they do get more involved with the Arbitration sanctions and verdicts, but its not likely that the WMF has any interest in doing so and its even less likely they will overturn one of their decisions.
