It looks ok to me, and the confusing function names could also pop up in 'well documented' code :)
Bottom line: the source is accessible.
I was not even aware it was minified like this, though. It will be on github soon under what I understand is an open source license - that was my main point.
edit: well, I looked at it again and it is not readable. Still, I have no reason to doubt it will be open sourced soon.
