All Dr. Tanenbaum is saying is that it would have been the classy thing to let him know, nothing more.

Professor Tanenbaum is one of the most respected computer scientists alive, and for Intel to include Minix in their chip and not let him know is kind of unprofessional and not very nice to say the least. That is his only (and quite fair) point.

> and for Intel to include Minix in their chip and not let him know is kind of unprofessional and not very nice to say the least.

I guess Minix' license, which allows this kind of behaviour, is the very reason Intel chose Minix in the first place. I imagine it would be very complicated to get management approval for informing Dr. Tannenbaum about the usage in Intel's ME.

IMHO if he has a problem with the way things worked out, he should have chosen a different license. For example the MIT license requires the copyright and license to be included in distributions.

The Minix 3 license contains [0]:

    * Redistributions in binary form must reproduce the above copyright

So it looks like Minix's license does require the copyright/license to be included in distributions.
