Let's look at newer documentation:
https://developer.wordpress.org/plugins/wordpress-org/detail...
> The use of trademarks or other projects as the sole or initial term of a plugin slug is prohibited unless proof of legal ownership/representation can be confirmed
The plugin is at https://wordpress.org/plugins/advanced-custom-fields and advanced custom fields filed for trademark last December https://trademarks.justia.com/983/21/advanced-custom-9832116...
Also
https://developer.wordpress.org/plugins/wordpress-org/plugin...
> We also don’t accept 100% copies of other people’s work
There's a clause which looks applicable https://developer.wordpress.org/plugins/wordpress-org/plugin...
> What happens to a plugin if the plugin owner gets blocked?
however the page says "Last Updated: 12 October 2024" and https://github.com/WordPress/developer-plugins-handbook/blob... (permalink at the time of writing this) doesn't have this section. So it really looks someone manually edited the page on wordpress.org without editing the source. Now, who has such permissions and has the motive to do this?
