As a programmer who didn't start out in C# it took me many years of hearing .NET being talked about before I started realizing people actually talked about an application framework and not the second largest internet top level domain .net. It is the only technology that I had that problem with, other pieces with a strange name I just look up the strange name and see what it is, but when I saw .NET in a title I just assumed it was about the top level domain, what else could it be?

I think that absolutely matters a lot for the health of an ecosystem.
