I believe it is the consensus that this is still OSD #3 compliant, as
long as the constraint is reasonable and technology-independent (OSD #10).

This is incorrect. GPL 2c requires that modified versions still:
"If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the
most ordinary way, to print or display an announcement including an
appropriate copyright notice and a notice that there is no warranty
[...] (Exception: if the Program itself is interactive but does not
normally print such an announcement, your work based on the Program is
not required to print an announcement.)"
Thus, if the original program displays a copyright notice (which is the
simplest form of attribution after all), warranty, etc. your modified
version must as well. Note that it doesn't require a specific form or
size, and it exempts derivative works that are non-interactive (even if
the original was). That is why GPL passes OSD #10 and GAP fails.
In one sense you're right, since OSD #10 seems to me a more precise
version of OSD #3 (i.e. you must allow derivative works to use any

Fails OSD #10, since not all programs need support web access. However,
I think this would also be invasive enough to violate OSD #3 outright.

This is possible. Of course, they shouldn't say the whole program is
