So Jason was getting 30-50% of a conference that made ~5m to 6m with TechCrunch's branding and Jason is surprised when Arrington feels like maybe he is the one getting screwed? I think maybe TechCrunch's name has a bit better branding than Mahalo...
Arrington is running a business - a startup - and he has every right to run his own conference using his brand. (Well, I guess AOL's brand now.)
