Radios and newspapers also did not present themselves as a way for the average person to make themselves heard. But you are onto something here - the problem is that there is a massive disparity in the power of an individual's discourse versus a radio or newspaper.
Now look at YouTube and Twitter. They amplify the voices of many average people, but only those who tow their political line. This makes it appear as though some ideas are more widely supported than they actually are. It's the same problem as with radio and newspapers, but it is exacerbated more than 1000 fold.
