And yet many report it works, at least for now, and the excess load due to scraping activity falls precipitously when Anubis or similar solutions are used. Maybe once this sort of challenge is used almost everywhere we'll see concerted attempts to get around it, but for now it is easier for them to just move on to another target.

Peanuts for the big players, but many (almost all?) running smaller scale scraping operations are going to find $5000 rather prohibitive, and they are unlikely to be able to integrate it as they are probably running a “stock” scraper that they didn't write themselves.
You don’t need to spend $5000 to obtain the hash rate of a $5000 device on a rental basis. You may have heard of this thing called “the cloud”. Obtaining very high hash rates is effectively free, largely as a side effect of the crypto bust.
Not sure why anyone would characterize these scrapers im general as all being fly-by-night operations that don’t have two cents to scrape together.
