wordpress, wp engine
The most darkly ironic thing about the whole WP Engine situation is that I never liked WP Engine very much, due to their intensely capitalist way of doing business, and they've long been on my mental list of "this looks like a FOSS profiteer that doesn't sufficiently contribute back".
And now, if anything, Mullenweg's bullshit has only increased my sympathy for WP Engine. They are still a capitalist enterprise, of course, but *so is Automattic*, and I'm no longer sure that the lack of contribution was actually caused by WP Engine's choices, as opposed to Mullenweg just getting in their way of doing so.
