No, I don't think so. For example, they have a feature that allows to follow a some twitter feed. Twitter does not have RSS feeds, so they wrote a code to handle that and charging money for that. I'm totally fine with that.
Reddit has RSS. Here is an example - http://old.reddit.com/r/all.rss . To subscribe to it, you need to pay 12 dollars per month to Feedly. And this I think is scammy.
Correct, Reddit RSS are not reliable, but most importantly, the rate limit always banned us in couple days every month. There are some tools available, but they will run into this issue eventually when they'll hit critical mass of users.
