Goodness.

Look at the GPLv2 (written by a CODER).

Compare it to the GPLv3 (written by these expert lawyers).

Which is clearer, more understandable, just more rational?

Which is the license that has the larger adoption on more code used by more folks.

And despite all the claims here, intent is going to matter. When you sue Linus and say the GPL doesn't mean what he and everyone else actually creating this code think it means, then he's going to say, this was our intent. And you are going to have a VERY tall mountain to climb.

Honestly, just quickly looking through the two licenses to answer a simple question... GPLv3 [1].

From a legal perspective, "simpler" documents tend to be less clear, because a lot more of the interpretation will rely on common law jurisprudence [2], and the "common" here doesn't mean "everybody agrees"--it in fact means "every jurisdiction has its own set of rules that may or may not translate directly in other jurisdiction."

Given that a software license is close to a take-it-or-leave-it contract, ambiguous interpretations are generally going to be interpreted in favor of the person who has the take-it-or-leave-it option--which in this case is not going to be Linus and co.

[1] The criteria I used: "how do patents interact with this license." From what I can tell, GPLv2 technically doesn't actually contain a clause where the licensor grants the licensee any and all necessary patents--it instead talks about what happens if the code violates a third party's patent. Admittedly, reading the GPLv2 to not include a patent license grant is somewhat of a malicious reading, but the GPLv3's verbiage here is pretty explicit: "Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version."

[2] I'm limiting my analysis here to US jurisdictions, because that's what I know.

If GPLv3 had been GPLv2 plus patent stuff and a few other things it'd likely have been very welcomed.

For folks following along, the GPLv3 is more than 2x the length of the GPLv2

"If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product"

Give you a feel for the GPLv3 style :)
