@jamesh @mcepl @blandford Sure. But it was nipped in the bud, and they've grown to embrace open source in a way that few corporate-driven open source products do.
Meanwhile, GTK has always been under the LGPL, but the community around that has been... contentious, to put it mildly.
There are plenty of examples on the internet, even in the GNOME GitLab of this.
Open Source alone does not protect you from toxic people. Caring about the community and stakeholders does.
