I just set up all the subreddits I still want to following in Reeder, an RSS app. I'm able scroll through the posts ad free. It the occurred to me that this is a loss of revenue to Reddit. Could RSS be the new target for onerous fees?

It could be the case that RSS usage is small compared to 3rd party apps like Apollo so not of much concern. It also may be the case that it isn't possible for Reddit to charge for the usage. If they can't charge, they may just disable RSS altogether. I'm only guessing. I'll take off my tinfoil hat now.
