Just shows that 1st Amendments rights are fine and should be used as people wish. However it is foolish to bite the hand that feeds you as these people learned. What one says as an individual is far removed from statements that cost your employer revenue and customer good will.

Good riddance, and it's a little too late. As soon as they published that article, they lost me as a reader.

Firing someone over it isn't going to change my mind.
