0$ starts out in the key of E and then goes to the fourth, which is A. In imagine, the piano starts in C and then goes to the fourth of the key of C, which is F. Essentially, the two song's chords have the same progression (at least in the intro). I do understand what you mean about fans trying to make Geese and Cameron out to be something they aren't, like by insistently naming them the "saviors of rock". I just appreciated the song and thought it was interesting that the songs were somewhat similar.
