It's done everywhere.
First time I picked up on it was years ago there was a company statement release about some new Alcohol flavoured Tim Tam Chocolates not actually containing alcohol (I'm in Australia). Apparently they had received complaints that parents were worried their kids would eat them and get drunk.
Firstly - the product had barely been out. How the fuck would parents know about them and there's obviously no way there could be alcohol in them. It's was obviously to get attention.
Make something up that you can release a statement on that the product or advertising doesn't cause harm or wasn't meant to offend anyone. Immediately makes people want to see or try the product or pay attention to the ad.
The memes stemming from this ad like a white kid wearing a top saying 'Koolest Kid in the Klan' (google it) just help further.
Everything in advertising is to get attention - this one worked amazingly as it even got a thread on getbig.
