The problem with that, if it's true, is that those people are less likely to be the content creators and more likely to be people who come to read what the 'serious' Reddit users post. Losing the hardcore group of creators will kill Reddit because then there'll be nothing for the casual readers to read.
Ultimately, Reddit's main work is to serve a small core group of people who post new content, and that content is what draws the rest of the users. They'll need those users to be happy in the first party app. That might be the case already. If it isn't, Reddit are taking a huge risk.
