Don't forget that AEG main objective was to establish a mega casino in it but never got the license and following the coverage around Philip Anschutz meeting with John Prescott, he now has some difficulty of backing off the venture (as he apparently promised to do if he didn't get the casino license).
The personality of P. Anschutz is quite controversial, from the origin of his fortune - oil exploitation of sacred native american soils, to his extreme conservatism (largely funding anti-gay, creationist, and "moral values" actions). All of this of course won't prevent him to take money out of gambling (if he had the license) and opening the O2 with shows popular in the gay community (B. Streisands, Elton John, Scissor Sisters). So we can suspect that P. Anschutz moral values stop where his wallet starts.
Of course people, once informed of his background and views are free to choose to feed the hand waiting to slap them...
