The only difference is that now echo chambers and communication speeds are so fast and far reaching that every kind of lie can spread like wildfire in seconds, with basically no consequence of sort. Now you can close yourself in a bubble without ever having to confront any view you do not like. I think it's kinda like how technology hasn't changed the reasons behind wars, or their intrinsic nature, but has definitely changed their impact and their scale. You can now lie yourself into and out of basically anything, without ever having to face the reality of what you are saying or suffering basically any consequence. I think that in one way or another, our society and political structures will have to evolve in order to take this into account.
