Seems like political tensions stemming from developments with situations Israel/Gaza/Iran and Ukraine have piqued the discontentment over accepting donations from organizations that profit from contracts with the US DoD.

The lead developer/organizer of the NixOS project seems to be pro authoritarian in their political values and this has also lead to an uneasiness amongst a number of contributors although things seem to be civil overall.

It seems that the "toxic" behavior from Hamilton was derailing technical discussions over concerns about the funding from military contractors.

I may have got some of this wrong, but it seems that everyone involved is trying not to draw attention to the broader political aspect of the schism in the community. So people out of the loop are having trouble figuring out what is going on.
