The Python Software Foundation (PSF) has withdrawn its $1.5 million proposal to the US government's National Science Foundation due to unacceptable terms in the grant agreement. The terms required the PSF to affirm that it does not and will not operate programs that advance or promote Diversity, Equity, and Inclusion (DEI) in violation of federal anti-discrimination laws. The PSF considered this requirement to be a potential threat to its values and mission. The organization is now seeking alternative funding sources, including donations.
