Not sure how I feel about this tbh, fair play if that's what he wants to do. I don't think it will make me stay with reddit. The community feel of lemmy and kbin is making me finally enjoy contributing again. Towards the end with reddit it felt so... Pointless.
I assume that once it's a subscription service most of that money will be going to Reddit, so you'd basically be paying for the privilege of not having to use their official app. That's just ghoulish.
