I didn’t read Solrize’s comment as saying “There shouldn’t be paywalls,” just asking the very legitimate question as to how they will interact with federation.
Interestingly, 404 just solved something kinda related: they developed a way for subscribers to get a custom RSS feed address, so they can access paywalled articles directly in their RSS reader. TMK, they are the first publication to do this. I imagine they would do something similar for federation. (I believe that if any of the custom RSS feeds show huge traffic numbers, 404 shuts it down, but I’m not sure)
