The one thing that interests me about the large CDN providers is active protection against DDoS attacks. As a small business that depends on its website being available to stay in business, how does it protect itself from DDoS attacks without using these large services? It would be too easy to take down an independent site by any malicious actor.

Other than that, yeah, I'm not a fan of the vast majority of all traffic coming from these 3 or 4 services.
