Instapaper does support paywall sites. I have a list of them, that when someone saves something it sends a copy of the page as they are viewing it only to them. If you subscribe to a paid site, you can save the content. I'm not really touching the money.

Instapaper is much bigger today than I could have predicted in 2008, and it has simply grown far beyond what one person can do. To really shine, it needs a full-time staff of at least a few people.

People want to download publications quickly and read them without cruft. Publications that started in print carry too much baggage and usually have awful apps. 'The Magazine' was designed from the start to be streamlined, natively digital, and respectful of readers' time and attention.
