Great examples. To this list, I'd add Amazon's ads. It's providing them with very obvious revenue growth. It's parasitic on their ecommerce business, though, in ways that for me and many others, harm the things that made Amazon popular in the first place. That'll never change, though, because that revenue has enough people attached to it that they'll fight tooth and nail to keep it no matter how much it harms the rest of Amazon.
