If it was a more legit trademark claim that would be one thing, a lot of OSS people think you can just name your project after something popular so you can coast off the reputation of the more popular product.

But since this is a BS claim, I think the following approach is totally appropriate:

- Have one person post the antagonistic garbage the OP deserves

- Have another person play the “rear guard” and follow up with the actual legal reasons they won’t comply.
