The jist is that subsidiary organizations of Aish have been heavily involved in the making of right-wing anti-Islamic videos, not to mention their extreme partisanship in US politics.
Now, I'm no fan of Aish, but this goes even beyond common sense. Isn't "kiruv" their stated purpose for being? I imagine they'll turn off a lot of potential recruits by their partisanship and their extreme social and political commentary. This stuff has nothing to do with their mission statement (http://www.aish.com/aishint/):
Aish HaTorah, founded in Jerusalem by Rabbi Noah Weinberg in 1974, is dedicated to revitalizing the Jewish people by providing opportunities for Jews of all backgrounds to discover their heritage in an atmosphere of open inquiry and mutual respect.
Except that they're driving away liberals or anyone who thinks in terms other than in black & white. But who needs liberal Jews to become religious anyway, right?
