There's a lot of reasons, but it's probably how Google makes most of their money - brand names end up being high value ad targets - at least 6+ years ago when I worked in that sphere of things (ecommerce, primarily). It's legit extortion.
I guess that's why - because extortion is immoral. Eventually, those paying the protection fees will eventually find someone better to pay or will stop paying when the protection doesn't show up.
Maybe it is today, but that's not how it's always been. The idea is that competition means the best product wins. But there's a lot it ways to degrade competition, not just monopolization. We're living in a lemon economy
