Not every tool on here fits everyone's ethics, but SOME tools fit SOME people's ethics. It's important to question what is ethical and what is not, but the question becomes moot if we never attempt to put the answer into action. Let's not hand-wring about "What is ethical?" so much that we never make any attempt to behave ethically.

I don't agree that all the tools on the list are ethical, but there are a few I plan to start using, because I do believe they are ethical and I didn't know about them before.
