I think it is easy to underestimate how big of a deal this is. Matt has a stranglehold on Automattic and Wordpress, it is not possible to remove his control over the ecosystem and he is volatile. Ousting him as CEO is almost certain to cause a major reaction from Matt, so, for Automattic to make this decision is a very big deal. The right decision for the long term but the hard decision. I expect we will see Matt try…
If he has 84% voting share, can't he just fire the board?
In this case? Possibly! Ann Dunwoody and Sue Decker look like independents, and he might be able to unilaterally replace either or both of them.
