Well, part of what I am trying to communicate is that the right to use a name is not always seen in the same way by everyone involved. I don't doubt Larry Wall's commitment to Perl, and he can make a dialect of COBOL and call it Perl for all I care, but when other people feel that they too have a stake in the brand, they get rather upset if things start to change under their feet. One sees this even with brands like Coke where disgruntled customers with no involvement in the making of the product get upset at changes in the form of the product.
To summarise, someone can be completely entitled to control a brand but they have to live with the consequences of their decisions. We've seen this with KDE and GNOME, of course, but also with Python and Zope. The interesting thing about Zope is that the project's output was actually renamed from Zope 3 to BlueBream precisely because the people with the right to use the name felt that continuing to do so was confusing to people.
