This is a pretty weird assertion - Voat doesn't have to worry about literally any of the scale problems Reddit does.
Reddit is just a cesspool, and it’s by design. Absolutely nothing to do with scaling problems.
Ed: to be clear, I use it logged in. I don't know how dark-patterny it is when logged out.
The site that pushes you to the app is just for your average idiot to find. A lot of the garbage we find obnoxious is training wheels for those idiots, and they love apps for everything as well. The persistent app nag is a benefit for the target user.
Sure it does. Once you reach a large enough scale you kind of need to do stuff to attempt to not be losing money on the development & hardware costs of such a large platform.. so you end up changing, even if it's not 'for the best'.
