As to the substance of Nathann's comments, most of this is really an argument about the GPL, or rather about how many of the potentialities in the GPL are acceptable to a given community around a GPL product. If you prefer not to contribute to GPL software, that is your right. But GPL software can be commercialized as a service or support, and of course anyone can apply for grants. So to avoid the possibility, do not contribute to GPL (or many other licenses) of software. CC-BY-NC would be a good place to look in that case, I guess?
I personally don't feel like my own (puny) contributions and the benefit I and my students get from Sage are mutually exclusive with the idea that others might also get benefit (monetarily or not) from Sage. Because any contributions are still GPL (that is also true of SMC) and hence I may still benefit from them. However, I - and many others here - understand completely if that licensing regime in the end seems inappropriate to any given contributor. For any who geek out about such things, I highly recommend reading about "anti-rival goods". The charge "who works at making people confuse Sage with his product" may have some substance, though one should point out again that SMC is GPL and could in principle be offered either at cost or free by any enterprising person or persons. Perhaps it would be worth a - separate - discussion thread on how much or little overlap between SMC and SageMath "advertising" is appropriate. Though I doubt it would be particularly conclusive; I assume there are a wide variety of opinions on this, and thus far it seems that most SMC-skeptics are willing to tolerate this for the increased visibility to Sage, regardless of whether SMC funds eventually are big enough to become available for Sage development (but let's hope!). -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
