I think "scraper vs siteowners" is a false dichotomy. Scrapers will always need to exist as long as we want search engines and archival services. We will need small versions of these services to keep popping up every now and then to keep the big guys on their toes, and the smaller guys need advice for scraping politely.

That's fair - though are we in an isolated bout of "every now and then" or has AI created a new normal of abuse (e.g. of robots.txt)? Hopefully we're at a local maximum and some of the scrapers perpetrating harmful behaviours will soon pull their heads in.
