Just like every other CDN or network service out there that is a proxy. Using a load balancer from a cloud provider that does TLS termination is the same risk. Of course it's by design because that's just how it works. You can't proxy TLS traffic without being MITM.

Please stop repeating the same exact thing instead of actually understanding what you're talking about, it's just misinformation and FUD at this point. You still havent replied to any of the other questions.
