If true, such chutzpah is a major miscalculation.
If there come about petitions to Leica to treat AppCam fairly, I'll happily sign. To let something so obvious and visible be appropriated without cutting the original developers in? Perhaps not a legal miscalculation, but certainly one in the realm of public opinion.
For anyone from Leica, if you happen to be reading: I'll reserve final judgement, but this looks pretty bad. Should I, someone who buys and uses your products, pay your premium prices so that you can cut out the idea people? Extraordinarily short-sighted of you, among probably worse indiscretions. I hope you realize that legal immoralities are still immoralities ...
Seemingly appropriate to the situation: "unfortunate, amiss, bum, crappy, dissatisfactory, poor, rotten, evil, immoral, iniquitous, reprobate, sinful, vicious, wicked, wrong, deficient, inadequate, inferior; careless, slipshod, defective, disordered, off, unsound; execrable, lousy, miserable, piss-poor, wretched; inadmissible, objectionable, unacceptable; insufferable, intolerable." (From a web answer to "synonyms for a 'bad thing.'")
If true, perhaps the most damning for Leica: "inferior."
Yes, we do have to give Leica a chance to tell their side of the story.
