To me it looks like a conflict of interests that Matt's using his role as the director of the non-profit to try to make a competitor pay his for-profit business (which it's worth disclosing that you are an employee of, edit: now disclosed) tens of millions of dollars.
Particuarly since WP Engine do already seem to contribute to the WordPress project/community/non-profit side, through events/sponsorships/open-source contributions. Even WordPress.org states "This organization contributes 5% of their resources to the WordPress project" under their "Five for the Future" program[1].
