From a European perspective, the online 'propaganda' has a very distinctively Ukranian, genuine and non-american feel to it.
Again, I'm not saying the Ukrainians didn't do this themselves. They may have. Or there may be some obscure books few people read in 30 years that tell the story of the companies NATO paid to prep the Ukrainians to win the propaganda war.
I'm pro-Ukraine (of course?) but I doubt there's anyone who's dipped more than a toe into poli sci and international studies who's not had this through cross their mind, on seeing how fast, consistent, excellent, and on-all-fronts Ukraine's public information warfare has been. It's not exactly a way-out-there possibility. And if they did it's not like that's necessarily a bad thing. Just... don't be surprised if there are some pieces about how much more there was behind the scenes to make that happen, in Foreign Affairs or something, that only politics nerds will ever read, in a few years.
They still upload combat footage to diverse repo, but nowadays its less accessible and more delayed, sometime 5 days "late".
is it less possible that regular people do this on their own than people do it because of some PR company and US government support?
you think it’s unlikely to have one adequate foreign minister and crowdfunding campaigns?
If you want - you can try your luck finding it, it was here, on HN.
Not to discount the possibility that they've simply knocked this out of the park themselves, but the "West" sure seems to be providing them a lot of soft support in addition to equipment, and some of that might be that kind of thing (I'm assuming Ukraine wouldn't be paying such a bill themselves, under these circumstances). The US government has been known to engage Madison Avenue & co. themselves, including for war-propaganda purposes, and not in the distant past.
