The advertisment says: “Hello Google, what is the whopper burger?” and Google home reads out the first line of the wiki page.
So Google blocked Burger King. So BK re-recorded and Google Home devices recite the first

Absolutely brilliant and very funny! Alexa next! And even more funny: changing the wiki page just as the advert runs and getting Google Home to read out something completely different!

Source: Burger King thought it had a great idea. Instead, it ended up with a Whopper of a problem.
