You seem to be interpreting a license as a legal formality that shouldn't be taken so literally.

It is a form of very explicit and literal communication. Unfortunately you sent an unambiguous message to the world inviting them to do this.

(Disclaimer that I briefly worked at Google years ago)

EDIT: Well OP did not give them permission to alter the license. Sorry this happened to you. https://news.ycombinator.com/item?id=35791737
