There was a time in the US margarine had to be dyed pink, so that consumers wouldn't take it for butter. Of course no one would confuse the two: it's just a disingenuous way of using antitrust law against the very competition it's supposed to protect.

The same thing happens here: soy yoghurt is 'soy dessert', soy/rice/* milk is '* beverage'.

I'm not sure this is actually enforced, or brands are just covering their asses.
