I thought the same thing. They could be using their legitimate user's connections.

But even if they're rerouting traffic through their users, and if they wrote that in the terms of service, I doubt any of their users know they signed up for this.

Which is not illegal, but still kind of sketchy.

If it's hidden in their terms of service, but not explicitly written on the content the user actually reads while subscribing, I consider this very unethical.

It would probably violate your ISP's terms of service as well. Not that I have any love or respect for ISP's but still.
