@marcan I've had timely responses in the DRM subsystem and constructive interactions because they use GitLab.
Trying to report a kernel bug via email never once got feedback (except for the one time where a Lenovo employee put in their weight).
For me everything points in the same direction: those rejecting modern tools like GitLab are gatekeepers, hiding immense complexity behind the pseudo argument of "accessibility".
Thankfully a lot of other projects do it right.
