A good example of an extremely small but extremely vocal minority doing their best to punish a company for not catering to their explicitly disallowed use case for no reason other than they want it. I'd bet this has 0 negative impact on their business.

That seems a bit dramatic.

What I learned from all this is that OpenAI is willing to offer a service compatible with my preferred workflow/method of billing and Anthropic clearly is not. That's fine but disappointing, I'm keeping my Codex subscription and letting my Claude subscription lapse but sure, it would be nice if Anthropic changed their mind to keep that option available because yes, I do want it.

I'm a bit perplexed by some comments describing the situation like OpenCode users were getting something for free and stealing from CC users when the plan quota was enforced either way and were paying the same amount for it. Or why you seem to think this post pointing out that Anthropic's direct competitor endorses that method of subscription usage is somehow malicious or manipulative behavior.

Commerce is a two-way street and customers giving feedback/complaining/cancelling when something changes is normal and healthy for competition. As evidenced by OpenAI immediately jumping in to support OpenCode users on Codex without needing to break their TOS.

They did not. Anthropic is protecting its huge asset: the Claude Code value chain, which has proven itself to be a winner among devs (me included, after trying everything under the sun in 2025). If anything, Anthropic's mistake is that they are incapable of monetizing their great models in the chat market, where ChatGPT reigns: ie. Anthropic did not invest in image generation, Google did and Gemini has a shot at the…

> making it impossible for other models to support their every increasing agent feature set (skills, teleport and remote sessions, LSP, Chrome integration, etc)

I use CC as my harness but switch between third party models thanks to ccs. If Anthropic decided to stop me from using third party models in CC, I wouldn't just go "oh well, let's buy another $200/mo Claude subscription now". No. I'd be like: "Ok, I invested in CC—hooks/skills/whatever—but now let's ask CC to port them all to OpenCode and continue my work there".

Credit to the early AI coding startups. They masterfully forked Microsoft VS Code and integrated frontier LLMs into a familiar IDE. Instant audience.

But it was only a matter of time before: a) Microsoft reclaimed its IDE b) Frontier model providers reclaimed their models

Sage advice: don’t fill potholes in another company’s roadmap.

Re: a) how can Microsoft "reclaim" their IDE when it was forked from a fork-able open source license?

Re: b) "frontier" models can reclaim all they want; bring it. that's not a moat.

I'm not sure if I should just post it plainly here since Anthropic might block it which would affect opencode as well, but here's a hint. After you exhaust every option and you're sure the requests you're sending are identical to CC's, check the one thing that probably still isn't identical yet (hint: it comes AFTER the headers).

I guess Anthropic noticed.

Idk if I disagree with anything you're saying, I'm just saying it's a very small minority that and are upset enough to both cancel and announce they are cancelling their subscription is all.

I think I just understand that companies only offer heavily subsidized services in return for something - in this case Anthropic gets a few things - to tell investors how many daily actives are on CC, and a % of CC users opting into data sharing. Plus control of their UX, more feedback on their product, future opportunities to show messages, etc. It's really just obvious and normal and I don't get why anyone would be upset that they removed OC access.

Exactly this. Ditto.

650,000 monthly active users is not "extremely small". I wonder how many total users Claude Code has?

I'm referring to the ones willing to cancel, especially ones who also feel the need to make a public statement about it. And I'd guess your number is high % churn, and even still CC is much higher.
