I would challenge you to show the effects of foreign influence. I haven't seen anything about what Russia did that even looked remotely effective. I recall reading an arstechnica article about it and I was shocked that they were citing posts with ~1.5k views... When facts aren't presented, the media make it sound like Russia had a major impact, but I can't find any facts that back that up.

I am much more concerned about foreign influence on the relatively centralized media outlets. For example, Bezos owns the Washington Post and does billions of dollars of business with China every year. All that economic activity gives china leverage they can use to suppress stories they don't like.

That is the real foreign influence to be worried about. Not them making posts and competing for attention with the same rules as everyone else.
