i guess this is what happens when huge, inflated egos clash. seriously tho, listened to their old stuff few years ago, didn't like it then, didn't like it now, but they've been a constant talk and pushed for for the last 2 years, they've gone very stereotypical "rocker" paths (word rocker used very loosely here.obv.) when it comes to their behavior (badmouthing and bad habits) and going very A-lister-ish with all the pap stuff, huge arenas etc. they're just one among these "huge" acts made out of the music companies that they labelled as "next U2", nothing weird...coldplay is another one, tho they keep their crap really tight and have been doing for years despite similar issues they had (or should i say certain members). this is just what happens when you break out and company wants to milk it the best they can. add big egos from the beginning and this is what happens. nothing weird, IMO.
AF should not even be mentioned in the same sentence as KOL. if anything, they're 3 times bigger band on stage and manage to finish each of their concerts without fighting or bit*hing on twitter, so..there's that. also, one of the best live acts out there.
