> I think the point is Google is really bad at understanding web apps, online services, or really any site that isn’t information rich.

You keep using that phrase, but it doesn't select for information richness, it selects for verbiage. This is at best orthogonal and more usually opposed to information richness.

Verbiage is the result of bad copy writing and/or lazy keyword stuffing. I don’t think they select for or reward verbiage, but for sure they’re not doing enough to treat it as a negative signal.

Well not directly, but you're heavily penalized for not keyword stuffing and then passing it through an AI tool until it is 'simple to read' (ie. says what you're trying to say extremely badly five times with almost-correct words to avoid anpiece of jargon).

As a result even the content made with earnest intent to communicate has to read exactly like blogspam in order to rank.
