Is this an academic paper? Telling a story the way the author sees it, causal relationships established as if they are obvious, no need to actually show they exist. This is indoctrination, not analysis.
As far as a critique of the actual paper, it seems to be predicated on the idea that democracy and freedom are synonymous when in fact they're orthogonal concepts. You can have tyrannical democratic structures, in fact that's what the founding fathers sought to combat in the original system they laid out which was less democratic than it is now (e.g. only land owners, people who have skin in the game, can vote).
"When the people find that they can vote themselves money that will herald the end of the republic." – Benjamin Franklin
Democracy does not guarantee freedom but it greatly increases the chances and distributes it more equally. Your chance of being "tyrannized" by the majority is less than 50%. A ruling class you aren't part of will tyrannize you.
That is the case in today's so called democracies. Just because you pick your ruler doesn't mean you have any say in the fate of society.
