reverse engineering an entire operating system isn’t easy

Have you noticed the the NT / Windows XP source code was leaked years ago. There's isn't much of a need to "reverse engineering", it's just about reading their implementation and providing an alternative implementation that doesn't copy code...

Paragraph «Don't», bullet point number 3: Don't look at any Microsoft source code. https://wiki.winehq.org/Clean_Room_Guidelines

Lol.

Imagine shooting yourselves in the foot like this.

Guess that rule was in place because some people would look at it and proceed to copy it. The rule should be "if you copy code from Microsoft you'll be kicked from the project and the code removed". While I see why this is place and what it protect the project from this is also a very big roadblock to the project's evolution and a clear example of what's wrong with it and why we still have compatibility issues.

Nope, because if you write code and they can prove you were influenced by leaked proprietary code in any way then they will sue the shit out of you and shut you down.

Also see Halt and Catch Fire for a show with this as a plot point. It's very real though.

That sounds difficult though. Didn't companies have to set up ethics walls to protect against lawsuits for things like that?

What are you talking about? There's copyright infringement that when you copy the leaked Windows source code into something like Wine or ReactOS and then there's reading it to understand what Microsoft did and coming up with an alternative implementation that will provide a compatible API for programs to use. There's no "gray zone" or ethical BS - it's either copied or not.

What are you talking about?

Ah the term I was looking for was "clean room"

See the bit about examples and IBM. While you could probably look, the easiest way to defend against a giant tech company's legal team is to do the clean room setup
