This isn’t VPN providers per se - most want to be able to control their own exit nodes.

There are however a fair number of commercial proxies that do exactly that, sometimes via consumer malware. I know several startup founders who have used them as a way to scrape lots of data and not get banned. Usually the interface they provide to the customer is just a normal SaaS “pay us money and give us a list of URLs and we will give you the page content”, and the interface they provide to the end user is a game or marginally useful utility, and nobody but the company realizes they’re doing something dodgy.
