I feel like this problem might be somewhat endemic to the US?

In my experience, US culture in general is a lot more positive about everything. Like, if someone from the US is not praising the living shit out of something, that means they didn’t like it.
Whereas here in Germany, it’s usually the other way around. If you don’t find anything to grumble about, that’s the highest form of praise.
Obviously, US culture isn’t one massive blob, the extremely positive folks are probably just those I notice the most, but maybe that’s also what the video author is fed up with.

Well, and then people from the US tend to also be a lot more positive about companies in general, presumably a remainder from Cold War propaganda. The journalists/entertainers from Germany and the UK that I watch, do criticize games quite directly…
