"Unfortunately" for whom? I'm pretty ok, even happy, with him out.
But, to be honest, I am not too well versed in the drama. IIRC it started because someone was building something on top of WP but was basically reselling something that was already free without contributing back? Maybe I'm mixing things up and I should really hit the sack.
Nevertheless, my concern lies mostly with the overall security of the platform, as I can imagine serious financial interests (and geological ones, too) might take the time to push out someone that knows the platform inside out.
