It's surely just in its bootstrapped growth stage.

If it wasn't for its annotation system, I'd put it in the realm of rather straightforward side projects. There are really good "readability mode" transformer libraries out there. And you can imagine buying a subscription to each of the major publications to bypass their paywall.

Paywall bypassing is something I would've expected from archiving services too but I noticed this is perhaps false. For example, http://archive.is/ycfsk archived the paywall.
