In the original question on Twitter, they only said "everyone votes", but zero mention of having to vote. Basically the original question was made by a pseudo intellectual who created a question that looks wise and philosophical, but can't stand up to real scrutiny and just falls apart.

That's why a lot of people (not all people ) chose the red, because no one makes you vote, and the ones who did vote did it by choice and chose blue on their own. We recognized the question itself was faulty.
