I think there are issues with Anthropic (and their ToS); however, banning the "harnesses" is justified. If you're relying on scraping a web UI or reverse-engineering private APIs to bypass per-token costs, it's just VC subsidy arbitrage. The consumer plan has a different purpose.

The ToS is concerning, I have concerns with Anthropic in general, but this policy enforcement is not problematic to me.

(yes, I know, Anthropic's entire business is technically built on scraping. but ideally, the open web only)
