What is most scary to me, is that these grants are not opportunistic (money is raised when needed), they are on an enveloppe basis (the amount to be distributed is fixed).
Essentially that means for every dollar not spent on, say, the PSF; then an other organization willing to denounce DEI is going to get these $1.5M.
I fear less for the opportunity loss to _proper_ organizations, and worry that activist anti-DEI/partisan organizations are artificially going to get a massive funding increase.
In that setup, it may be the lesser of two evils for the PSF to accept that grant, if only to deny a more partisan organization to get this funding.
