In a resouece-constrained way. For every word of propaganda they were able to afford earlier, they can now afford hundreds of thousands of times as many.
It's not particularly constrained - human labor is cheap outside of the developed world. And propaganda is not something that you can scale up and keep reaping the benefits proportional to the investment - there is a saturation point, and one can reasonably argue that we have already reached it. So I don't think we're heading towards some kind of "fake news apocalypse" or something. Just a bunch of people who currently write this kind of content for a living will be out of their jobs.
I’m curious why you think we’ve already reached a saturation point for propaganda?
There are still plenty of spaces online, in blogs, YouTube videos, and this comment section for example, where I expect to be dealing with real people with real opinions - rather than paid puppets of the rich and powerful. I think there’s room for things to get much worse
