No it's about toblerone adding more space between the chocolate. You're getting less product for your money. Nothing new, but toblerone is fucking delicious, so people are mad.
Toblerone has always been overrated. Sell it at the airport, and everyone loses their mind and hoards it like their lives depended on it. Sell it at the supermarket, and people just shrug.
I exclusively buy it from the supermarket so I don't know what you're on about. Who the fuck buys chocolate at the airport when you can just bring it in, only liquids are banned.
