Track Record

In January 2025, Mullenweg deactivated WordPress.org accounts of several community members, including two planning to fork WordPress and the CEO of the WP Community Collective nonprofit. He also dissolved the WordPress sustainability team after learning it existed. Mullenweg acknowledged the lawsuits 'could potentially bankrupt me or force the closure of WordPress.org.'

In September 2024, Mullenweg publicly attacked WP Engine as a 'cancer to WordPress' and demanded 8% of revenue ($32M) as trademark licensing. When WP Engine declined, he blocked their access to WordPress.org, disrupting over a million websites. He then seized WP Engine's ACF plugin without review. WP Engine sued for extortion, unfair competition, and defamation. A court granted a preliminary injunction restoring WP Engine's access. 159 Automattic employees (8.4%) took buyout packages to leave.
