Me for one. Adding an auto-updating IP address blocker to my personal blog site would probably cost more than setting up the whole site did in the first place.
We're talking about sites that make their living via subscriptions. They should have a great interest at blocking archive.is, which is, by the way, the only service that can reliably bypass many paywalls. Clearly whatever they're doing is not easily replicated.
Sorry, but I wasn't. I thought that was clear from "can't afford the cost of keeping up-to-date with the Google IP list".

Agreed, and many should have a budget to suit. So I conclude archive.is has put a lot of effort and cost into its defence. And all for free to us, the users.
