For the most part, RECAP just eliminates inconvenience. For matters of widespread interest, RECAP saves thousands of people from having to make PACER accounts. But the stuff that ends up on RECAP, for obvious reasons, tends to be the small minority of cases that the public is interested in, and for the most part that content is practically (sometimes literally) free.
I think RECAP rules a lot and I have the plugins enabled in the browser session I use to read PACER. I'm just saying, it's not really a liberation of all of PACER.
