I think the idea here is that all these reverse-engineering projects are _saying_ they're doing clean room implementations for quasi-legal protection.
So they are claiming to follow the legally protected "decompile -> write spec -> new code from spec only" process but they're likely skipping the "write spec" step, and hoping/assuming that it's basically impossible to prove that they're doing so.
