If this is really so, then the reason would be that Google intervenes on the basis of illegality: animal cruelty is illegal, whereas pest control is not. This discrepancy between how we pretend to protect animals but still do plain "pest control" is weird (this is a weak word), but this is a quirk of our "modern" society. The law is made democratically, so that just means that a majority of the citizens think that it is not ok to hurt animals, but that it is ok to use mousetraps. Blame on the lack of awareness of the society. But then, in turn, this means that not a lot of people flag the video, if the majority of them still think that pest control should be legal. If not, then now should be the right time to change the law of the country where you/me live.
