By that standard, how is say Bellingcat not a pro-NATO propaganda outlet, when the founder was even invited to be a senior fellow of Atlantic Council, a think tank whose members have included luminaries such as David Petraeus, Colin Powell and Henry Kissinger?
The Gray Zone is not a quality outlet, IMO. They're certainly too light on Russia, and worse, bad at distinguishing genuinely damning stuff and spun fluff.
But they should still be able to take the public's funding, if the public wants to fund them.
I think we just need more reciprocity laws in international relations. Russian and Chinese journalists should be equally as constrained as American journalists in their countries.
