We asked the OSI mailing list for guidance

We got an answer by Mr. Sullivan, director of the FSF
(http://projects.opensource.org/pipermail/licensediscuss/2014-January/001423.html), stating
•
that even RMS discussed this issue (java script trap) &
•
that even the FSF votes for a link based solution : the
license text is not directly included into the package but
delivered by an extra request..

It contains nearly the same text like the GPL-3 - except §13, the “Remote

users interacting with it remotely through a computer network […] an
opportunity to receive the Corresponding Source of your version by providing
access to the Corresponding Source from a network server at no charge […]

to generate, install, and (for an executable work) run the object code and to
modify the work, including scripts to control those activities.
However, it does not include the work's System Libraries, or general-purpose
tools or generally available free programs which are used unmodified in
performing those activities but which are not part of the work”.
