I guess that's one, IMO, really weird way to look at it.
I read that post and I read it as...
The graphics mode of the remaster of Chrono Cross is so bad that even the power of the PS5 isn't enough to make it run as well as the original does.
Basically, "Holy shit, even with this uber powerful PS5 console, the graphics mode of the remaster runs like shit."
It's a comment on how bad the remaster is and not a comment on the PS5 in any way, shape or form.
And I'm pretty darn sure that is what they meant by that. I can only think that the console war mentality in some people then somehow manages to twist that around to somehow imply that the PS5 isn't powerful? Or some other weird conclusion like that.
