I agree that this seems to be a major PR blunder. For a company, that makes most of its profit promoting family experience, to kick Walt's nephew out on his butt on the lame pretext that he's too old (the clause has been repeatedly bypassed prior to this) is very unseemly.
Also, on a subjective level, Eisner has always kind of made my skin crawl. Roy elicits that warm, fuzzy feeling I remember from seeing Walt on The Wonderful World of Disney on Sunday nights.
JMO, of course. For all I know, Roy could have been a major wrench in the works, but it just looks bad.
