Hard disagree. Sure their docs are bad, and it's sometimes buggy. But to me cloudflare is actually innovating and trying to offer "new" infrastructure. Durable objects and workers are super cool. R2 has free egress, isn't it insane that they could pull that off?
If what you want is a VM to run postgres then there are other offerings that would be much better.
Not saying they aren't evil though, they probably are, but the infra stuff is cool.
