As spotted by @DuaneStorey on X, the “WP Engine Tracker” says more than 16,000 sites stopped using WP Engine since late September, which is when WordPress.com parent company Automattic started its public campaign against the third-party hosting service. Meanwhile, Automattic’s response to WP Engine’s lawsuit claimed the company “failed to plausibly allege specific financial harm.”
The very second website in the file they use to track recently-moved websites uses substack (now).
