Thanks for relaying that ought-to-be canonical example.

It may not be owed/due, but common decency suggests you give a heads up.

In Intel's case I'm guessing there was a contending motive in that they preferred not to draw attention to it.

> common decency

Large companies don't operate according to human social norms like this. It's important to be reminded of this fact from time to time.

At some point, no matter how big the company is [1], there are humans redacting, validating and applying the policy.

[1] Ok, maybe Google have just bots for this also. ;)

You can put that clause in your license! Something like:

  If you use this software in a commercial product, you are required to
  make an attempt to send me an e-mail letting me know about it, 
  because it's just nice to know.

Of course that would piss off the lawyers because now if a developer uses your software and doesn't e-mail you, you could sue them. But it's not like big companies always respect licenses anyway :)

Tanenbaum, to me, always seems to have a massive chip on his shoulder

Credit is certainly owed under MIT, a copyright notice must be included.

(I wonder where Intel shows this copyright notice; in principle, it should come with every processor or product based on the processor. Probably in the same place where IME itself lives…)
