I’ve read your entire comment and still think that the GP is an appropriate joke. You gave a good overview, in clear language, trying to be as concise as possible. The result us still quite long, in fact I guess it is long enough that most commenters won’t read it in full, just like a typical T&C document.
Contracts are long for good reasons, but excessive contract length is a real problem.
The US is set up to be regulation-lite and litigation-heavy. As such, contracts tend to be rather encompassing, lest they be vulnerable to litigation.
You also seem to be missing that your parent and the GGP are not the same account. The original comment was written by grellas, a longtime HNer and valued contributor. I doubt grellas runs sockpuppets considering he had a YC connection at one point, IIRC.
