>Last week, in a blog post, Mullenweg said WP Engine was contributing 47 hours per week to the “Five for the Future” investment pledge to contribute resources toward the sustained growth of WordPress. Comparatively, he said Automattic was contributing 3,786 hours per week. He acknowledged that while these figures are just a “proxy,” there is a large gap in contribution despite both companies being a similar size and generating around a half billion dollars in revenue.
It seems to me that it isn't a simple "dispute." Automattic is contributing to WP org, but WP Engine isn't. If WP org was completely neutral, they still would have reasons to side with Automattic over WP Engine on this.
