2. Nominative use allows companies to refer to things by their name. It isn't obvious that "Wordpress Hosting" or "Wordpress plugin" is a violation or causes consumer confusion. Does Matt wish for all companies in the ecosystem to stop referring to their products as Wordpress Themes, Wordpress Plugins and Wordpress hosts?
It's worth noting that for years Wordpress.org has routinely referred to companies as "Wordpress hosts"
For example: https://learn.wordpress.org/tutorial/migrating-your-wordpres...
They don't seem to find it confusing and I suspect it would be difficult for Wordpress to launch a legal claim given tolerance of and direct use of those terms.
