Work Ethics is the simple answer to this argument. I consider signature campaign as a job since I'm being paid. So I will not express any statement that will affect the company that paying me to post here in the forum because I'm the one who voluntarily join on the campaign.
Are there any rules against it? otherwise, anyone can join, regardless of principle. I think the people who have the most right to judge this are the campaign managers and BenCodie himself. We do not need to interfere with his principles and impose our principles on him.
This is correct. But this doesn't justify what he is doing is ethical for the company sake that paying him. Bottom line we don't really have any say to this. Maybe let the representative of the casino check it and decide what to do.
