2c of the GPL is actually somewhat controversial. I don't know whether
anyone actually thinks it makes the license non-free, but I suspect a
number of people would be quite happy if it were removed from the GPL.
That said, it's much weaker than the proposed "clarification" for
reiserfs4:
- As you point out, it's only for interactive use. While not (directly)
a freeness issue, that does significantly reduce the burden; since
it's being used interactively you've ruled out a lot of the more
irritating times to display a verbose message.
- It defines what must be presented clearly (i.e., copyright, no
warranty, where to find the GPL), but in the loosest possible terms
("display an announcement including" the information, rather than
dictating text).
- The stuff being displayed serves a clear legal purpose and cannot be
expanded/added to by downstream modifications. For example, two works
which both display such a blurb, when combined, need only display one
such blurb, rather than the combination of two different blurbs.
Personally, I consider this to be about the outside limit wrt freedom.
