Don’t entertain meetings without compensation from megacrop. But the project is open source. The author provided the right for them to take it in any way possible and copy it. If I’m not mistaken the MIT license allows what they did.
I’m assuming the complaint is more about Microsoft duplicity in asking for information as opposed to the forking of the code. The latter is fine - the license explicitly allows it.
The "notice" is the literal license file. It is illegal to strip someone else's license from their work. It doesn't matter that they replaced MIT with MIT, because they stripped the author and attribution from it.
