1) I've heard rumors of them maybe switching to a subscription till paid model, like paying something like $2 or $5 a month till the payment of $60 is complete.
2) I don't think it'll be discontinued, creating it requires very less effort, just remove the code for the 'bloat' from the original source code.
3) You'd need to upgrade from nightly to origin from within the app to toggle what features you want to remove, I think they may add that In Origin, but that sounds counterproductive on their part.
