Ignoring the executive drama (on both sides) it is in bad taste to build WPEngine off an Open Source project and barely contribute back to it.

It's probably a case where their version is so heavily customized they don't spend much time on the fundamentals. But still. I wonder if that had a petty rationale as well. Relationships are important in business.

Harder to justify contributing back when the open source project is so tightly coupled to your biggest for profit competitor.
