Considering they fully own all of the IP present in the OPs work, I would imagine they are within their full rights to just take it without asking. OP is lucky not to get a takedown notice and judging by his attitude he knows it. Good to see people playing nicely together :)

The games were already playable online on archive.org [1]. My project is just focussed on the old flight simulators.

Especially I wanted to have a very light-weight emulator which starts within milliseconds. The major part of the emulator downloads with just 24kB compressed. I suppose I have reached the goal.

It’s MIT licensed. They don’t need to ask. They need to add his name to credits and/or send an email about what they did.

It’s basic courtesy (plus MIT license, if you prefer).

You need to use 3 or 4 clause BSD not MIT if you want to get in credits.

courtesy cannot be enforced, that's the point.

I bet if it was 3 or 4 clause BSD, somebody will say that "open source is open source, I don't care".

No credit is owed, no thanks are due. This is an unavoidable effect of usuing the MIT license over something like GPL.

Andrew Tanenbaum on choosing MIT for the MINIX project, which was used by Intel + the IC as a base for the Intel Management Engine (emphasis mine):

"The only thing that would have been nice is that after the project had been finished and the chip deployed, that someone from Intel would have told me, just as a courtesy, that MINIX was now probably the most widely used operating system in the world on x86 computers. That certainly wasn't required in any way, but I think it would have been polite to give me a heads up, that's all."

If you'd like to avoid a large company profiting off your work without attribution, don't use MIT.

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…)
