You are free to not use it. You are not free to use the API provided specifically for the product, which you are not explicitly paying for, for a different product.
You can of course use OpenCode or any other project with the API, which is also offered as a separate product. People just don't want to do that because it's not subsidized, ie. more expensive. But the entire reason it's subsidized is that Anthropic can use the data to improve their product.

This is grade A, absolute crap. It's subsidized because everyone else is subsidizing it, and everyone is doing it because they are trying to lock their consumer share.
The solution is quite simple. Just get the FTC to forbid tie-in sales so that we don't get the huge corporations using their infinite resources to outlive the competition. Anthropic/Amazon/Google/OpenAI/Facebook can offer any type of service they want, but if the access to the API costs $X when offered standalone, then that is the baseline price for anything that depends on the API to work.
