Oh, I'm sure it is. The problem is that they could sue me anyways.

That can happen any time anyway. But they would have to show damages. And even though you'd be on the hook for legal fees - at least initially, defending such a simple civil suit isn't that big of a deal financially.

Or ... just do open source under an alias.

Agreed, they're trying to scare folks.

When I looked into something similar I found that while companies will fight tooth and nail to not sign away rights to a specific idea/effort, the law is very much on the employee's side as long as you don't use corporate equipment to do it.
