I agree with many of the points you make here, and it is right to think everything in the current music industry context.
I just believe that that there are a few good reasons why most of the fans didnt welcome this new single that are irrelevant with the inudstry's climate.In my opinion these seem to be the most important:

1)The title: definetely the least important issue,but its not wrong to say that most of us were misleaded and anticipated a more rock sound,especially with the buzz 'that this is our house' created only a month ago.
2)The feeling of a poor effort.Literally Bon Jovi (Jon and Richie) have written this song MANY times before.So, it's not a matter of whether we would have liked this song if it was on an album,but whether we feel that this is an appropriate and honest attempt to deliver a leading single for a GH.Jon has said many times that he writes from his heart,the most honest place he knows,but I don't think this song justifies this statement.
3)The Circle. This is for me the most important issue. It became obvious really quick that Jon and Richie didnt stick to what they were saying about how proud they were about this record.The album was not at all supported by the band live,and only a few tracks were performed,with the highight of 'Brokenpromiseland' being played only once.
According to the band,when they were launching their career,they had to play hard every night original material and try to win the crowd.So,for me it is unacceptebale for such a band who was raised with this philosophy,to not at least make a decent effort to work and promote these songs.By releasing this single and the GH album, the circle is officially dropped by the band way too soon,something that makes Jons words about the need to have a voice and comment on the big changes during the last years just empty and meaningless.
4)The production.This is a second official Bon Jovi release in one year(!!),and they sound different.Its not a matter of whether its bad or good,but whether the cirlce and this single's production fit.I feel that the circle implied that the band is going somewhere,and suddenly 'what do you got' terminates everything by sounding different.It gives the feeling of disorientation and the sense that Bon Jovi is going backwards way too soon.

So, if you think of all these factors (consiounsly or subconsiously) in context, you realize why fans are disappointed.I dont believe that for these big mistakes the record company and the music industry are to blame.Bear in mind that Jon said that he actually told the company to wait for the GH, because he wanted to release the circle.It was his decision.And if part of the agreement was to release the GH2 in November,then 'What do you got' doesnt sound as a natural transition from the circle to the GH2,which could be in the benefit of all four:the circle,the GH2,Bon Jovi and us,the fans.
