It's not news that the quality of the show sucks these days, and Howard's taken "phoning it in" to a new level. It's also not news that he makes a huge effort to keep fans from hearing "sensitive" information now. Whether it's callers that are too honest, the truth about Robin's illness, Robin's angry walkouts, silence on the Artie situation, negative comments about Beth's Hollywood friends, or whatever else... the staff have to go to great pains to keep raw information from hitting the air.
Thinking about both these facts together, though, is extra lame. For someone as "hardworking" and "honest" as Howard... it's especially pathetic that the only thing he's careful and diligent about anymore is suppressing honesty on his show.
