Not being able to use certain words reduces our ability to effectively discuss those topics, as well as the likelihood that we will try. By obeying such restrictions for the sake of monetization, you implicitly state that your stake in a given issue is less important than money, which means your opinion on said issue can be effectively disregarded, as it can be bought. If you truly care about something, you will not accept a monetary incentive to censor words related to that topic.
