It would have been friendly, but FWIW they seem to have forked my project in mid 2017, so I'm guessing it's an experiment and got shelved and later revived.
So it's easy to imagine a scenario where the people who ultimately released it last week weren't really aware of how much it uses external libraries - mine, and also a 3D engine called Babylon.js (who also weren't contacted).
Amazing - you are given the power to choose your own license and choose how you want people to view your source code, yet people are STILL unhappy and surprised when you comply in the exact way you wanted them to.
