Ah didn't realise full context in this specific case. I was referring only to "a fan legally constitutes an aircon". So, if the only thing in an AirBnB is a fan, saying it has aircon is misleading.
If you're just reading the headline easy to get it wrong. But these "outrage" stories often have another side.
