> I don't even think they care about the CLI

No they actually do, basically they provide claude code subscription model for 200$ which is a loss making leader and you can realistically get value of even around 300-400$ per month or even more (close to 1000$) if you were using API

So why do they bear the loss, I hear you ask?

Because it acts as a marketing expensive for them. They get so much free advertising in sense from claude code and claude code is still closed source and they enforce a lot of restrictions which other mention (sometimes even downstream) and I have seen efforts of running other models on top of claude but its not first class citizen and there is still some lock-in

On the other hand, something like opencode is really perfect and has no lock-in and is absolutely goated. Now those guys and others had created a way that they could also use the claude subscription itself via some methods and I think you were able to just use OAuth sign up and that's about it.

Now it all goes great except for anthropic because the only reason Anthropic did this was because they wanted to get marketing campaign/lock-in which OpenCode and others just stopped, thus they came and did this. opencode also prevented any lockins and it has the ability to swap models really easily which many really like and thus removing dependence on claude as a lock-in as well

I really hate this behaviour and I think this is really really monopolistic behaviour from Anthropic when one comes to think about it.

Theo's video might help in this context: https://www.youtube.com/watch?v=gh6aFBnwQj4 (Anthropic just burned so much trust...)

That's not at all what they're saying, though. It's just nonsense to say "you can't recreate our CLI with Claude Code" because you can get literally any other competent AI to do it with a roughly comparable result. You don't need to add this clause to the TOS to protect a CLI that doesn't do anything other than calling some back-end—there's no moat here.
