Ask HN: Cloudflare R2 seems too good to be true. Do the economics make sense?

It's hard to believe CloudFlare R2 charges zero egress compared to 9 cents per gigabyte from all the big cloud providers.

How can it make economic sense for CloudFlare?

Will this last? Will it be cancelled?

I feel like I'm stealing when I use it, I'm so used to being charged 9 cents per GB.
