Reddit doesn’t have the internet infrastructure FB has where they were able to monopolise the internet of whole countries in certain parts of the world.
And the wider they cast this dragnet the more users will be caught up in it, the more will slowly leave, the less content will be created, the worse the platform will get.
I think for the future of reddit you only need to look at digg.

Also is there a reason they can’t just distribute proton? It’s open under BSD, so they’d be free to do it.
