It might be, but I know that I had 200TB of real traffic via Cloudflare this month, while I paid for 8TB on my upstream. Running services of that scale would be utterly impossible for me and probably a lot of other people without their help, so it's definitely empowering.
Are you saying that 95% of traffic is malicious or 95% can be cached?
In either case 200TB is a 1Gpbs link with 70% utilization.
Something what a cheap (<100eur) server from Hetzner can sustain, for static content of course.
8TB is also not that much at all. As an example our household uses about 2TB per month, both working from home + watching netflix sometimes.
