Also, as a website owner, these residential proxies are a real pain. Tons and tons of abusive traffic, including people trying to exploit vulnerabilities and patently broken crawlers that send insane numbers of requests, and no real way to block it.

It's just nasty stuff. Intent matters, and if you're selling a service that's used only by the bad guys, you're a bad guy too. This is not some dual-use, maybe-we-should-accept-the-risks deal that you have with Tor.
