@monsieurborni @LWN I would say associated is a bit of a broad term. I would go with "confused" instead. For example, let's look at the Red Hat ecosystem:
RHEL, CentOS, Fedora. None of these legally related projects can be confused with each other. The numerous derived projects of Fedora (Nobara, Universal Blue, etc) aren't confused with Fedora proper.
But SUSE and openSUSE? Before even getting to Leap or Tumbleweed one just sounds like a free version of the other.
