Think about that for a moment.
ClosedAI were able to use being "open" to market their start-up. They were able to use that to attract funding / investment. Then, they transitioned away from that with a convenient excuse when it came time to launch their product.
Is that not a grift?
This is the same playbook that Hashicorp and Reddit used. They were "open source".... Until they weren't. Reddit even had an open API... Until they didn't.
