Do you want those who improperly classified info to be punished, as well?
As that is neither a violation of oaths, nor military code, nor US law, I think the appropriate response is to determine who is at fault and hold them accountable through the normal democratic process.
Actually over classification is a federal crime. The same law that set out the classification levels etc also made it illegal to knowing over classify material simply to keep it out of the public eye. Now that aside I still feel from what I know what Manning did was wrong and he should be punished to the full extent of the law.
Even big, established companies incentivize employees with various equity-ish options,
Incent. The word is incent.
It's one thing to choose how to license your own code; it's quite another to insist that others license their code the same way, simply because it may have some tenuous connection to your code.
I don't think the connection is tenuous. Is the theme intended to be run as part of Wordpess? Yes. Does the theme work without Wordpress? No. Sounds like a derivative work to me.
IMO there is a big difference between coding to an established interface (let's say POSIX) and writing an extension (theme/plugin/whatever) that is intended to run only as part of a specific piece of software (like Wordpress).
If you want to create your own non-GPL blogging software to run your own themes, go for it. If you want to save time by using someone else's work, you have to abide by their rules. I am pretty sure that this definition of derivative work has not been tested in court yet, but it really has nothing to do with the GPL specifically.
We're forced to purchase car insurance with no government-provided option, BY LAW.
How is that a bad thing? You might feel differently when your car is totaled by an uninsured driver, who has no money to pay for your medical bills even if you sue him.
This is a good time to punt work.
