There are plenty of alternatives for other models like opencode et al, and you can always just set ANTHROPIC_BASE_URL with claude code to have it use another provider. I don't see why they need to do anything in addition to that.
My only request would be for claude code to be a bit more open, less obfuscated and to accept PRs - but I understand the unwillingness of also wanting to manage what would be a very popular open source project.
And of course, not the same, but Aider still exists and is still a great tool for AI dev.
It's interesting how everyone is suddenly OK with vendor lock-in, quite a change from years past!
Claude code is completely closed source and even DMCA’d people reverse engineering it.
