Umm, I don't see how that follows, actually. Granted, we're trying to avoid that the *other* direction, ie. avoid mentioning non-free "competition" to free tools, but that's a special case, philosophically; here the idea is that "any time we can give the user more information, we both win." I don't recall anything in any license that prevents the change, for example... can you find any examples? I haven't seen any indication that informal mention *wouldn't* be a good idea; if we can include it in the policy, then we can start getting maintainers of non-free packages to add the pointers. I'd still be more impressed with a more formal pointer, though, so that tools can tell the user automatically...
