Some people have a view of open source contributors as some sort of amorphous mass of strangers, and that leads to unrealistic suppositions. The contributors aren't really amorphous, they exist, they're knowable, they have personalities and jobs.

A project such as wordpress(.org) depends very strongly on those who do the work. And in the case of Wordpress, that's some spare-time volunteers, some employees of other companies, but the biggest group is Automattic employees. If you do most of the work, as Automattic does, the project depends on you and you get to call the shots.
