Are you contending unless otherwise specified, people should be mandated to continue spending money with companies?
I'm allowed to do business or not do business with any company for any reason I like. Cofounder funding a political party with one of their goals being to brutalize immigrants? No thanks. Contractor wearing a company shirt was rude to me on the elevator? I'll check the competition. Maybe I just don't like the color of their logo?
I'm allowed to define my morals and what I would consider violating those morals would be with monetary support and no half baked slippery slope argument is going to change that.
What exactly is the allowed reasons for doing or not doing business with people?
