Yes, because I can't read or modify your files over the internet just because you chmod'ed them to 777. But with Clawdbot, I can!

It's vastly different.

It's more (exactly?) like pulling a .sh file hosted on someone else's website and running it as root, except the contents of the file are generated by a LLM, no one reads them, and the owner of the website can change them without your knowledge.
