Because it's obvious an ever growing group of comic book writers are fed up of the confinements of the big 2 publishers and are leaving to pursue their own original properties.
I'm more impressed with the successful people who never needed the big two to have a successful career
its all well and good that people are off doing their own thing, but they weren't "fed up" when they needed pay checks, its only after they had enough money and clout that they found their moral outrage at the business practices of the employer who took the financial risk on them
good for you, you stuck to your guns when it benefited you
(oh, but you'll still write for them if you get the call or you fall on your face)
