The USSR heavily censored content, were they stepping closer to fascism? I don't think you're using facism in the right context here, maybe you meant something else?
As someone else pointed out, Reddit's not a democracy so they're not starting as one either. Unless you count their private corporation as a democracy of sorts, but then they're most likely acting in their shareholders' interests. Maybe you meant the word authoritarian instead of fascist?
The US is a democratic republic and they are a US based company, so they should lean towards the laws under which they exist. I'm not playing this semantics game with you.
