I believe you mean the GNU Assembly? https://gnu.tools/
I'm not sure to be honest, I signed up to the mailing list but never received any mail. but from what I could see and gather from the gossip, it seems like some of the people involved became the objects of targeted harassment, where anywhere their names would appear (ie hacker news) someone would seemingly chime in out of nowhere with comments like "you know they are a (((Marxist))) that support a woke-totalitarian agenda to end software freedom to appease their moral anti-scientific agendas, right?", and I think this harassment caused a lot of folks to retreat from public development & free culture.
