I’d suggest that, for the cost of an extra domain name, and a boring logo, they could probably significantly increase their subscriber base.

Here’s an idea. Do this with a giant ass logo. Put a banner underneath it with a link saying something like “Add this for FREE to your own business’ website!”

It would have two main benefits. First, it’s still a giant ad for their company. Second, it would shame the company into sponsoring because now everyone can see how cheap they are.
