Re: Failed English comprehension
I'm not making any assumptions. The letter states that they included only the source for OSS they used. The github repo where he has uploaded the files does not contain any of the modifications or derived source so they have NOT complied with the GPL. Again I have not made any assumption about the licence, the components that have been provided are GPL licenced.
So let me repeat: They have not provided their sourcecode. They have not complied with the GPL.
