Re: Unfortunate turn of events?
Well, looking at it objectively, Apple here are the common denominator and the most litigious, so my guess is they've decided to draw a line.
I guess the more interesting question is why? A number of options spring to mind - in no particular order:
1.Fear of defeat - possible and with the precident it would set potentially very damaging.
2.A genuine waking up and smelling the increasing expensive legal coffee - again possible but I think probably the most unlikely reason.
3. Management time - Cook has talked about the next big thing being imminent and time spent in litigation is time spent away from what has to be more important stuff for Apple. Irrespective of the merits of whatever it is they're talking about launching, and it good be "insanely great" a turkey or anywhere in between, one thing I am sure of is that Cook won't want any distractions from it either internally or in the press, so by winding down hostilities he gets the most benign environment he can engineer to launch into.
On the other hand it could just be coincidence.,.
