People are getting way too bent out of shape over that "medium customarily used for software interchange" bit. It doesn't mean github. It doesn't mean "the medium I use most commonly".

Basically, if you think courts are going to be OK with interpreting "download from this FTP site" as acceptable but "download the same tarball from Drive" as unacceptable, you're fooling yourself.

Drive is fine, given the spirit of the license. It's merely inconvenient.
