I don’t know if the WordPress project has any official ties to the Free Software Foundation. I did a quick Google search but didn’t come up with anything.
We are a project whose members/contributors value diversity and inclusion, and we have done a lot of work to make our official events, (WordCamps) welcoming to everyone, including people with disabilities and children.
And we, as a project, one around which a thriving community has formed, are free to disassociate ourselves from him and his comments.
Whether we like it or not, we are the gateway for a lot of people who normally wouldn’t touch free software on their own.
