Actually, we just started a paid plan with them. We had been considering the move to GitHub, but wanted to see how this scenario played out before doing so. The issues Julie-Ann faced are important to me personally and to my company, and we couldn't support an organization that allowed such behavior to remain unchecked.

I was impressed by GitHub's response in this case. A founder being forced out* of the company s/he founded, especially one as white hot as GitHub, is not a decision made lightly. It signaled to me that the issue had been taken seriously, albeit too late. But I am comfortable supporting them going forward.

*That Mr. Preston-Warner was forced out is my own between-the-lines reading of his resignation once he lost support of the board.
