I'm going out on a limb and say that I'm not convinced that there's been a mass fan exodus anywhere, even in the UK. I think there's a media backlash (because it makes great click-bait) and maybe a few vocal souls who are getting a lot of the attention over this, but I've met a lot of UK fans in my travels and to a person, they're still on board according to their social media. In the US, I haven't noticed a drop at all beyond the media latching on and certain publicity whore fans giving interviews for still more attention, it's almost as if it's a non-event here. All the shows I went to this year in the US and Canada (7) were sold out or nearly so and the Broadway run which I didn't get to was a huge success.
So I can't vote, because my vote would be "Surprisingly well" for the new album, but I don't think there are any fans to return, as I don't think many have actually abandoned ship. I'm not looking for (or expecting) any apology or denial of M's views, because where I live, we're all entitled to believe what we want. His beliefs effect neither his voice nor his shows; I still enjoy the hell out of both. (Now, if he starts ranting on and on about his favorite causes at shows like Bono did, I'd be happy to reevaluate my opinion, because that's part of the reason I walked away from U2 after 25 years)
