They are more worried about building a moat than anything else. They want people building integrations that are difficult to undo so that they lock into the platform.

So basically what happened:

1. Anthropic realized their models weren't enough of a moat.

2. They built tools so they could expand their moat.

3. People don't want to use their tools, they want their models, and use other, better tools.

4. Anthropic bans the use of better tools, taking advantage of their model superiority to try to lock people into subpar tools.

"I don't have enough of a moat so I'll use my little moat and pretend it's a big one" doesn't sound like a great strategy. All they're doing with this anticonsumer behaviour is making sure that I'll leave the moment another model works for me as well as Claude does.

Ironically, they are now playing against their own models that can relatively easily build wrappers around any API shape into any other API shape.
