This is actually going to be the topic of my next blog post. Reading through the Associates Program Operating Agreement (https://affiliate-program.amazon.com/gp/associates/agreement...), it seems like there is a decent chance Philanthropist would be in violation of something. However, that agreement is for associates, so I'm not sure if those rules would apply to a browser extension.

Also, I mostly built the extension for myself so I could easily support one of my favorite podcasts. There are only about 10 other users and since I don't really plan on advertising the extension, I doubt the user-base will ever get big enough to warrant concern from Amazon.
