For me, there's a difference between modular synths and guitars in the same way that there's a difference between experimental and pop music. Or an outside comparison - go and chess. The former is small and the latter is big. That causes the communities of the former to be rather close-knit everybody knows one another kind of places whereas the latter are rather anonymous. So when a bully enters, the latter will shrug and go on minding their business. Whereas the former will close ranks and protest. There's more at stake than pure business. When Behringer clones current products of existing companies, they're threatening the livelihoods of well respected members of the community and, in many cases, friends.
So while I prefer having correct information on what a module does in the module's page, I consider it to be essential information as well when it's a rip-off.
