The entire saga started due to WP Engine "forking" WordPress.

So problem solved? My only criticism is that 1) Mr. Mullenweg should have held tighter controls over the IP and 2) the direction to the community that they are encouraged to use "WP" as a prefix for their business names and products was ultimately a bad one leading to this mess..

WP Engine's "forking" consisted of disabling the revisions feature by default.

As someone who's personally been bitten by this particular WP Engine misfeature, describing this as a "fork" is disingenuous at best. The average Linux distro ships way more out-of-tree changes than WP Engine ever did.
