It went platinum as a single. Anything platinum isn't a flop. So I can't see why people are shading it or labelling it a flop. It isn't. It went top 20 on Pop radio, top 20 on Billboard, and is platinum. It clearly was a hit single.
Just listened to it for the first time
Literally wanted to turn it off after the opening line
Anyway it's radiofriendly and Taylor is a huge seller so that's why it's doing good
