Actually I think many posters didn't read the original article, or that it is poorly written:

He isn't actually saying that Germany didn't lose the battle of britain
He is saying that Brits venerate it, and Germans seem to have forgotten/ignore it (perhaps because from their point of view, because they never felt that they lost it.)
It's a different question than one about whether Germany did or didn't lose the BoB - the question is why does it mean so much to Brits, and so little to Germans.
