alt Hacker NewsSearched the USPTO trademark site, no trademark for "WP" registered by the WordPress Foundation.
WP is GPLv2. Is WP Engine distributing their modifications without releasing their changes?
No trademark issue, license seems fine. From what I can tell this is nothing.
The Trademark is for WordPress, not WP. The name "WP Engine" isn't the alleged problem, it's their usage in their hosting packages like "WordPress Core".
