Not today, but tomorrow maybe, Claude could prevent you from implementing anything that looks or smells like a competitor product, for example.
You think they wouldn't?
They already put limits on machine learning research, with explicit intent to sabotage competitors

Developing a competing AI model with Claude is already against their TOS, and there was a period where they silently degraded quality if they thought that's how you are using Fable. People were not amused and presumably Anthropic currently does not sabotage your attempts, apart from regular TOS enforcement
