The problem is that YOU have no knowledge whether a copyleft license is
being violated or not. It is a gross arrogance on your part presume that
because it is CC-BY-SA in one context that all such uses must be CC-BY-SA.

If someone write a piece of music and releases it under a CC-BY-SA
license, they can also allow uses under other conditions. Now assume
that you hear that music in some TV advert is the advert CC-BY-SA? Not
if the creator of the music relicensed it to the advertizer minus the
copyleft requirement. Being an outsider to the agreement between the two
parties you simple do not know.
