> The abbreviation “WP” is not covered by the WordPress trademarks and you are free to use it in any way you see fit.

According to WP Engine:
> Automattic CFO Mark Davies told a WP Engine board member that Automattic would “go to war” if WP Engine did not agree to pay its competitor Automattic a significant percentage of its gross revenues – tens of millions of dollars in fact – on an ongoing basis. Mr. Davies suggested the payment ostensibly would be for a “license” to use certain trademarks like WordPress, even though WP Engine needs no such license.
