First let me say that I understand that NASA's proposed license doesn't require tracking, it merely encourages it.
I, and others, think that a tracking requirement would not be appropriate in an open source license.
1) Tracking presumably requires reporting back to some organization. What happens if that organization disappears? Does it then become impossible to distribute the code? If it does, the code would clearly no longer be open source.
Detailed tracking is done anyway through web logs. And, companies dissappear all the time - no big deal there. It's their data so they can discard it if they like. I would rather know that more details about the product's use are being tracked than not. When a company tracks the usage of their product they have an easier time gaining support from onlookers, which is good for the product.
I want to write to my congress people and make a case for NASA spending a lot of money on open source development. It's more compelling to do that if I can point out where the product is being used.
Perhaps you're nervous because of the hype that licensing lawsuits get in the press? The rest of the NASA license guarantees free, unhampered use so tracking does not present a discrimination issue.
Tracking information is meant to be held private, so it wouldn't be appropriate to release that inforamtion to the public anyway. Tracking information is absoutely key to a developer's ability to guage the success of their product. For example, if you have reliable numbers to compare your downloads with, say sales figures from a comperable well-known product (e.g. MS Office), then you can promote that product more effectively.
2) It is generally considered to be desirable to permit open source software to be used anonymously, such as by a dissident under your least favorite form of government. Arguably preventing the possibility of anonymous use violates OSD #5.
Once a product under GNU is initially downloaded, the person can distribute it anonymously. OSD #5 simply states non-descrimination - which means that you won't restrict the availability of your product to a particular group/caste/class/industry, etc... I maintain that as long as non-restricted access is granted non-descrimination is complied with. Besides, non-descrimination typically is not meant to ensure that you cannot know where your product is used.
3) While free software is not identical to open source software, they are generally congruous. The FSF specifically forbids tracking: http://www.fsf.org/philosophy/free-sw.html:
I think what I was pointing out before was that the standards for open source definitions are arbitrary and varied. I would like to stick to opensource.org's criteria on this list.
You should also have the freedom to make modifications and use them privately in your own work or play, without even mentioning that they exist. If you do publish your changes, you should not be required to notify anyone in particular, or in any particular way.
GNU specifically states that changes will be submitted back to the authors. That requirement, if enforced, provides much more stringent tracking than what NASA proposes. But, I also point out that this requirement in GNU is not enforced at all, generally, making that provision useless, and makes the language in the GNU license an empty requirement on its face. For the GNU license it means the requirement might not be enforced by a judge even though the requirements are there. Why put such a requirement in the license if it's not going to be enforced?
This is a key difference between NASA's license and the existing ones - enforcement of the requirement. If NASA requires registration, then fine, but I expect NASA to make an effort to actually enforce the requirement. And, the efforts to do that are clearly stated in the license itself, making the license more consistent between intent and implementation than many other licenses (on that point).
