I think the fact that you've paywalled Reddit RSS feeds which are free is scammy. I get asking money for improving something, but there is no way to just subscribe to Reddit feeds as is.
How is allowing feeds from a particular site a "feature"? They actually had to do extra work to block those feeds for the free tier.
Maybe Gmail should add a paid feature to allow email from Amazon.
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.
