@chris WPEngine has fantastic customer support and handles Drupal as well. Matt's posturing is silly, if given the choice to host with WPEngine again I wouldn't hesitate.
Sure, maybe WPEngine doesn't contribute to the project as much as Matt would like, contribution supports his goals not theirs. However, plenty of WPEngine clients contribute back to WordPress and other projects.
Shaming Automattic's competition is gonna backfire.
