I must agree with the OP.... the generally under-informed public may well interpret that as an endorsement that it is acceptable to crowd that many fish into a small aquarium.
This is ESPECIALLY true if they see it on Discovery, Animal Planet, National Geographic, etc!
Granted most/all of us here on AA forum know this is wrong, but the under-informed will form their opinion based on what they may have available, even if it IS just a TV show! My own mother though a goldfish would do fine in an outdoor 'pond' (it was 10G) with no real filtration or aeration! That poor fish now swims in a much bigger tank with sump filtration and crystal-clear water!
