I'm really sorry if some people credit Sage without properly crediting everything Sage depends on. We've gone out of our way to make the architecture of Sage clear. E.g., look at the description of Sage on our website: "SageMath is a free open-source mathematics software system licensed under the GPL. It builds on top of many existing open-source packages: NumPy, SciPy, matplotlib, Sympy, Maxima, GAP, FLINT, R and many more. Access their combined power through a common, Python-based language or directly via interfaces or wrappers." The "and many more" is a link to each component of Sage. I also often tried in talks to always define sage as: (1) a distribution of open source math software, and (2) a Python library that ties them together. Given the mostly volunteer nature of the project, many Sage developers are mostly concerned with creating software to support their research (which they then want to get back to), instead of worrying about the very important social points that you bring up.
