Tanenbaum isn’t looking for money from Intel
That decision was made when he released it as open source. That said, many big companies understand they have an enlightened self-interest in supporting those open source projects on which they depend, via donations, contributions, and programs like GSoC. Even so, it would be shameful to beg, and he probably doesn't need financial support.
In light of that, this:
one of your engineering teams contacted me about some secret internal project and asked a large number of technical questions about MINIX, which I was happy to answer. I got another clue when your engineers began asking me to make a number of changes to MINIX
is particularly lame. The least they could've done was do the work themselves and submit patches. If I were the maintainer, I'd have told them I'd consider patches they submit but no way would I do free work for Intel (perhaps with exceptions for requests that I'd already really wanted to do - sounds like most of these probably weren't).
