Not really, its more like saying no one needs another windows when linux exists. By "no one needs" i mean the world needs open source sandbox building blocks that are up to the challenges of the current age, no closed source solution can be a fundamental building block for the world to become better and more secure. No non-local building block can be at the foundation to anything that makes the world better and more robust.
That's a very narrow and technical person's point of view.
You might need it open source, the majority of the world doesn't care, like they don't care Windows is closed source, or like AWS is a "cloud" running somewhere else. Both of them are building blocks that made "the world better and more robust".
Users might not care but the people building such things (us) do care and must care so that we can provide a product for those users which does what it says.
If you don't care that's fine. You go run the Claude Code "sandbox" and let it put your entire home directory on a public pastebin. Anthropic guarantee it will exfiltrate your data in the most secure way possible.
The rest of us want verifiable sandboxes which we can fix if they are wrong.
