When you’re at the point that sharding is an important consideration, "just use X" doesn’t apply for any X anymore (except "the expertise in your own team" etc).
The advise is clearly targeted at those with a scale orders of magnitude smaller than Notion.
I don’t think anyone is claiming "you should just use Postgres" without knowing about your constraints. And if they do, I guess that’s a useful heuristic to know when someone doesn’t know what they’re talking about.
It’s still good advise for the 95%, even if you yourself fall outside of that. Part of the reason you get paid well is to know when advise applies and whet it does not, and to not waste energy arguing in either case.
