Why would they if it is limited to a few, maybe a couple, of poorly built lenses? To announce anything will automatically suggest the problem is bigger than it is, which is fuel to the flames as far as Digiloyd with his axe to grind is concerned. Why would a person, or company, want to open themselves to being used to pedal his bias? I mean, if Nikon built a few bad lenses, but the overall production run was going well, would they make a big announcement out of it? Of course they wouldn't, so why expect it from Leica?Problem is Leica did not say anything officially so far.
This conspiracy theory with secret emails and a mole in the heart of Leica is pure bollocks, a fantasy. No real journalist would even open up the possibility of suggesting they had a secret source of information as a teaser, because the source would know what a big gob they are dealing with.
