The GNOME Foundation takes donations[0], I think it would probably be good if they had some way to signal that you only want the money in a legal defense fund (especially given that sometimes they put Foundation resources behind controversial things which I myself don't want to support).
Nonetheless I'm throwing some money into the pot, hopefully it is used to fight this troll case, which thankfully may be so facially ridiculous that it is thrown out.
Look at the staff list https://www.gnome.org/foundation/staff/ . It's top heavy with useless people running "diversity initiatives" and "anti-harassment teams" and only one Gtk dev. If they had 10 developers then maybe there'd be a place for these people, but at the moment I don't agree with their priorities.
I'd happily donate to a legal fund to fight this lawsuit though.
The role of a typical FLOSS foundation is to enable development by providing neutral infrastructure and organizational efforts, for example organizing conferences & hackfests with travel reimbursements, boring accounting & paperwork, maintaining trademarks, avoiding legal risks; the actual development will be done by interested companies and individuals.
I think part of what flukus was getting at is not supported by that staff page. GNOME has outreach and sponsorship programs, but they all seem to be gender discriminatory, and focused more on external social causes than on the quality of GNOME software.
GNOME Foundation could probably just use GitLab.com, it wouldn't take a full time staff if their focus was infrastructure. It seems like the GNOME Foundation is predisposed with gaining institutional power over the symbols of GNOME, to egoistically control the community.
Nonetheless I'm throwing some money into the pot, hopefully it is used to fight this troll case, which thankfully may be so facially ridiculous that it is thrown out.
