Seriously, do something that might make your employer look bad and see how long you keep your job.
Who determines if it makes the employer look bad?
In the case of A&E it is the people that watch the channel, and the sponsors/ad providers. Currently, the people that watch the channel and this show are in support of the duck dude speaking his mind, so it isn't hurting the viewers. I'm not sure about the sponsors and ad providers. I think how things are turning out show that what he said did not hurt A&E, but shutting him and the show down has hurt A&E more than anything.
Therefore, from a business perspective, I think they made the wrong decision. I think ultimately this will hurt them. This show had put A&E back on the map, which up till now I think everyone forgot they even existed

They just killed their one main show that brought them revenue. Financially, this could be bad for them. Their decision could backfire.
