i think it's only casual listeners and those kind of "fans" that come and go that are not very happy about her. I have a japanese friend who buys every single cd of hers and who said no word on Ayu's relationship or how bad the PVs are. In fact she loved the PVs and the songs.
I can say only one thing here, she accepted the fact that it's no longer her being number one, she had her peak and was on the wave, got a gazillion of records and is now just making music. The ones who can't let go are fans, and i am also not sure that Japanese fans care about that stuff either. It's probably only people overseas
