Or you could just not use Amazon at all until you feel that they're in line with what you expect of a company. Consumer activism is a difficult set of choices.

Or you could just not use Amazon at all until you feel that they're in line with what you expect of a company. Consumer activism is a difficult set of choices. If you stop supporting by purchasing from a company, you run the risk of that company failing/struggling and things getting worse. If you do support them, you run the risk of allowing their behavior to get worse. There's no objectively moral choice in a vacuum and points to be made for both actions. Be as informed a consumer as you can be and purchase mindfully. Speak with others about the issues you feel are important and try to improve things. That's really the best you can do.
