Elementor isn’t “campaigning against WordPress”, it’s trying to make WordPress more attractive to people who have been frustrated with it.

If they want to help the community grow by sponsoring WordCamps, it’d be ridiculous to ban them from doing so.

It’s difficult not to view this as Automattic having an issue with a company providing a popular alternative to Gutenberg, particularly when it’s highly probable Elementor will launch a SaaS version that will compete with WP.com.

Competition is healthy, trying to prevent it isn’t.
