No, we're not confused.

The *GPL* is a copyleft license, and as a result it is incompatible with
licenses that extend its requirements.

That leaves the question of whether CC-By's attribution requirement is a
superset or a subset of the attribution requirement in the GPL.

It's even possible that it depends on what the author has asked for in
their license grant statement (with their CC-By licensed work).

However, the GPL provides a very explicit set of requirements for
attributing authors and/or contributors, so it sets a standard for what
is "appropriate to the medium", which may be consistent with CC-By.

I believe there are even some changes to the wording of GPL v3 which may
remove doubt that may have existed with GPL v2.

Of course, it goes without saying that CC-By-SA is incompatible with
GPL, because they have conflicting copylefts, regardless of the
attribution issue.

Cheers,
Terry
