WordPress has escalated its feud with WP Engine, a hosting provider, by blocking the latter's servers from accessing WordPress.org resources -- and therefore from potentially vital software updates. From a report: WordPress is an open source CMS which is extensible using plugins. Its home is WordPress.org, which also hosts resources such as themes and plugins for the CMS. A vast ecosystem of plugins exists from numerous suppliers, but WordPress.org is the main source. Many WordPress users rely on several plugins. Preventing WP Engine users from accessing plugin updates is therefore serious, as it could mean users can't update plugins that have security issues, or other fixes. WordPress co-founder and CEO Matt Mullenweg recently called WP Engine a "cancer" and accused it of profiting from WordPress without contributing to development of the CMS. Mullenweg has sought to have WP Engine pay trademark license fees -- a move he feels would represent a financial contribution commensurate with the benefits it derives from the project. WP Engine doesn't want or intend to pay. Mullenweg argued that if WP Engine won't pay, it should not be able to benefit from resources at WordPress.org.
