There is no problem with criticism that is concerned with most mechanics of gameplay.
I truly believe Digital Foundry style nitpicking about graphical fidelity, lighting, and cloth physics has been an accelerant for the current state of budget bloat. It's devoid of joy.
FF7 Rebirth is magical - a technical marvel and they have a good portion of the enthusiast community believing that it's in some kind of unplayable state.
This is often mitigated by PC nitpicking which is concerned with showcasing cutting edge hardware, but for console releases, it ruins the discourse.
Imagine if BG3 had come out on console only. The criticism around its image quality issues and graphical bugs would have drowned out any of the positives - perhaps sinking Larian in the process.
Weird. Total opposite for me. Criticizing something that is subjective as gameplay mechanics is fine to a degree, but I constantly see people complaining about "ruining" a game because XY is nerfed. Also, at some point a game might just not be for someone. Like, I am super tired of the soulslike formula, but that isn't a criticism towards it.
Technical stuff is inherently more objective, for reviewers and QA teams alike.
On that note, I have absolutely no idea where this "nitpicking" criticism comes from towards DF. They are a bunch of guys who are really interested in the technical side of real time rendering, and hardly nitpick games. IMHO they are a bit too understanding on some issues (picture quality and devs making FSR piss blood), but even that is explained by them very well.
And when they do criticize stuff, it is often refreshing and a much needed megaphone for the PC community, especially around frame time consistency, shader compilation and asset streaming related stutters. All of which were largely ignored until people started talking about them when they got out of control. And without DF we wouldn't have had the ability to articulate the problems towards devs who seemingly didn't really test or looked into this.
There was only one recent critical DF video that I didn't really agree on and that was DS Remake. I felt that the traversal stutter was not nearly as bad to warrant a more negative tone overall, and the other stuff was quickly fixed, but I might have missed some stuff that others encountered.
When capital G Gamers take DF videos and run with it, it is mostly thanks to other factors, and just general drama generation. For example, Helldivers 2 was adored by the community even if I would classify it as a semi-technical mess, and my complaints were also voiced by Oliver, although he certainly has a less harsh general tone than others. DF videos generally get blown out of proportion when a game has other problems (real or imaginary).
