It's a waste of time made necessary ONLY because of copyright law. As I explained.

As is THIS ENTIRE COMMENT THREAD.

And 10,000x other comment threads exactly like it, with you fools arguing back and forth for 300 pages about the subject.

What a complete waste of time and energy. Thanks, copyright law.

Nonsense. People reimplementing stuff to see if they can is unrelated to copyright. See the many implementations of vi.
