Increasing CLs server load & increasing their bandwidth costs was morally questionable, it became clearly immoral once they knew CL didn't like what they were doing.

I'm not entirely sure I agree with this part. If I say, "John's website is at this address," John doesn't get to say "HEY! I get to decide who links to me," because copyright isn't for facts, it's for content. That's why I disagree so vehemently with the PadMapper decision: All they were saying was "There's a CL post for this address." That's not content, and it's certainly not enough content to replace the functionality CL sued over.

Padmapper mined data (apartment locations, prices, number of bedrooms, URL to Craigslist post), not creative presentation. Even if we believe that it's somehow morally reasonable for Craigslist to have copyright over the text of user postings, the data Padmapper required was clearly not copyrightable. This was a CFAA case, not a copyright case.
(Yes, in practice Padmapper also displayed descriptions and photos, but they could have avoided doing so, and the service would still have been useful.)
If we're talking about morals, then the fact that CL only got copyright via a click wrap assignment, and that most postings aren't copyrightable because there's no creativity, and that the actual creators (posters) benefited from this access, I don't think things held up.
I'd also be surprised to find a real increase in load, if the scraping service served end users. Otherwise those users would be requesting directly to CL. And, if the 3rd party service worked by riding on the back of users (say, via a browser add-on), would that suddenly change things?
