I don’t think your edited title is that clarifying, and in fact, muddies the water by glossing over some key details. Chiefly, Congress doesn’t fund the OTF, they fund the US Agency for Global Media, which in turn uses some of their money to fund the nonprofit OTF; the OTF then uses their money to “support open technologies and communities that increase free expression, circumvent censorship, and obstruct repressive surveillance as a way to promote human rights and open societies,” per their 501©3 non-profit mission statement.

OTF has its own board, and they operate independently from the government, though their operations are tied in a roundabout way to how Congress decides to allocate funding.

That F-Droid got a piece of that pie is a good thing, especially in light of the current regime and how they’re basically giving the middle finger to Congress.
