The thing about Ayre and public comment on the Suarez affair is that it was a very complex situation.
Coming out as the head of the club and strongly condemning racism would have appealed to almost everyone else except the manager, the players and Liverpool fans, and coming out in support of the manager and Suarez left open the possibility of Liverpool being ridiculed and criticized by the rest of the football community beyond Liverpool fans and possibly by a wider audience. It was a minefield with the possibility of big losses as well as gains either way if he had started to talk.
You can argue that what should have been done is work to engineer a resolution to the problem behind the scenes to make it go away. You can also argue that not talking wasn't hanging Kenny out to dry but trusting his ability as the primary spokesperson for the club to be able to handle the situation. In fact, I'd say you can paint his not talking in any number of lights depending on your preconception of the man himself.
I think a lot of what we do is start with a conclusion and then work backwards and add speculation dressed as facts or one of many interpretations dressed as the only possible interpretation to try to justify that conclusion.
