Which is why most folks use CloudFront like AWS recommends, which is typically free for services to route through. Prices for CloudFront egress are competitive with what you described for other vendors. I don't know anyone paying $90/TB out to internet on AWS.
The Cloudfront pricing page you cited is just as bad, except the free tier for Cloudfront traffic is 1TB/month rather than 0.1TB/month. The pricing is just as bad above that. It says "Free for origin fetches" but upon further research, seems like that just means you won't pay twice by also having to pay for your traffic to get from its origin to Cloudfront.
Okay, I stand corrected. Now my question to you is how are you generating all these terabytes over the internet? And would data transfer costs really be a significant portion of your bill at that scale regardless of cloud provider? Not video transcoding resources, AI capacity, GPU capacity, etc.?
You're talking about the equivalent of completely saturating a gigabit Internet connection for over two hours per terabyte. A high def video stream from Netflix is only about 5 megabits/sec. 4K is 15 megabits.
67+ simultaneous 4K streams for two hours. Or 200+ simultaneous high def streams. Or a metric fuck-ton of web resources.
And you think you're going to find a provider that will allow you to send those kinds of volumes for $10/TB or less AND have relatively few outages AND stick around because their business model is sound?
By all means, point out who these unicorns are. Sign me up!

Were you trying to route S3 directly out to the internet?
