I'm struggling to find a comparison but I think it's probably because there's a clear and easy migration path that they can shut it off for users who pay the company, and expect support, and not that it was free and in beta. I don't mean legally acceptable because it's spelled out in the ToS, but acceptable to the community.

seriously? you're being disingenuous

codex being in beta meant it was improving, not that it'd vanish overnight.

it's not about "getting what they pay for," it's about showing some respect to users who trusted the service.

So? It's still not cool.
