You can't be an author if you aren't the author of a principle or the principle is too generic. If the principle is already open source (e.g. on wikipedia, has a creative commons license) you can submit it but not claim you are the author for it and submit it under the same licensing terms (CC-BY-SA) as long as it doesn't break the license.

Codifying the principle for the first time takes effort and people can iterate on it to make it better over time. Many people may have had similar thoughts before, but if it's not a general principle already being used the first to turn it into a principle - to put a stake in the ground - benefits everyone and can help improve everyone's capability.

I believe the author should be rewarded for that effort, as long as it is their own unique work.

Then being able to create your own lists for unique situations. Say "Lupire's CTO list" or "Lupire's management principles" and to share that with your team or as a reminder to yourself.

Of course you should always be able to export it and put it in a format that's useful to you. And that's been really important to the design. From using markdown format to embedding license information and meta data with the principle, it should help a lot with portability.
