They can pick the default reasoning effort:

They can decide what to keep and what to throw out (beyond simple token caching):
> On March 26, we shipped a change to clear Claude's older thinking from sessions that had been idle for over an hour, to reduce latency when users resumed those sessions. A bug caused this to keep happening every turn for the rest of the session instead of just once, which made Claude seem forgetful and repetitive. We fixed it on April 10. This affected Sonnet 4.6 and Opus 4.6
It literally is all in the post.
I don't worry about anything though. It's not my product. I don't work for Anthropic, so I really couldn't care less about anyone else's degraded (or not) experience.
They control the default system prompt. You can change it if you want to.

Don't see how it's an obstacle in allowing third party wrappers.

That's actually a good point. However I still don't think it's an obstacle. If third party wrappers were bad, people simply wouldn't be using them.
Defaults matter. A large share of people never change them (status quo bias, psychological inertia). Having control over them (and usage quotas) means Anthropic can control and fine-tune what this fixed subscription costs them.
And evidently (re, the original article), they tried to do so.
Allowing third party wrappers doesn't mean Claude Code would cease to exist. The opposite actually, Claude Code would be the default.
People dissatisfied with Code would simply use other wrappers. I call it a win-win. Don't see how Anthropic would be on a lose here, they would still retain the ability to control the defaults.
I have no idea what the share of OpenClaw instances running on pi was, or third-party wrappers in general, but it was obviously large enough that Anthropic decided they had to put an end to it.
Conversely, from the latest developments, it would seem they are perfectly fine with people running OpenClaw with Claude models through Claude Code’s programmatic interface using subscriptions.
But in the end, this, my take, your take, is all conjecture. We are both on the outside looking in.
Only the people who work at Anthropic know.
