What are the times you are referring to? The times of breaking company policy? You can argue all you want that he was sacrificed on the alter of liberal witch hunting. But the reality is that his employer found it reasonable enough to have rules regarding what you, as a representative said employer, are allowed to say, then you will be fired. Full stop.
No one is talking about a lawsuit, or revoking his citizenship. He is perfectly entitled to his opinions. If I go and shit in the company sink because it seemed like a victimless crime and that all the waste water goes to the same place, I will expect some sort of company push back on me. And sure as hell wouldn't expect anyone to start a fundraising campaign so I can take my special brand of colon evacuation somewhere else.
Engineers should help engineers in times like these.
