Was it ever not one? They protect a lot of DDoS-for-hire sites from DDoS by their competitors. In return they increase the quantity of DDoS on the internet. They offer you a service for $150, then months later suddenly demand $150k in 24 hours or they shut down your business. If you use them as a DNS registrar they will hold your domain hostage.

Where can I learn more about the 150k in 24h?

yeah, GP completely fails to realize that Cloudflare has always played both sides. that is their entire business model, and it was transparent from the beginning that they would absolutely do the same here.
