I wouldn’t ascribe this quarter’s woes to some grand machinations. Intel’s situation really does seem that bad and they’re years from recovering (if they do)
Standard practice in a turnaround is that if a loss is unavoidable anyway, you might as well make it as bad as possible (i.e. jam future bad news into it).
But as you point out I am not privy to Intel's actual practice here and haven't bothered to read the 10-Q.
