Indubitably unfair, as you say. Mea culpa. A great little scope, which I used a lot.

Still, having upgraded to the F6.9 fluorite doublet the improvement in chromatic aberration is striking nonetheless, and I see that William Optics ended up including a fringe killer filter in their package, so I guess sufficient numbers of people thought it was annoying enough to prompt the change. But CA is one of those things that troubles some people more than others. What can I say? YMMV, perhaps?

All the best, and have a cool Yule.
