I honestly believe that 90% of the people jumping ship has less to do with the fact that Britney isn't promoting and more to do with the fact that the song is flopping.
I'm sure a lot of you guys would still be here if the song was selling 500k first week with no promo and you know it, personally i would've loved a performance first week but let's not act as if every artist these days promotes in the first week. Like i said yesterday it's just clear she's faded and isn't as big as she used to be considering it's not only freefalling in the US but also in Canada and France, aka two of her biggest markets.
We'll see how it does with the video, but it's nice to see how many Britney stans are only here for success.
