This is a lesson on marketing. "No Kings" rolls off the tongue. Monarchy invokes autocracy/dictatorship, it's an easy transition into connecting that it's the opposite of democracy.
"Rulers" kind of include democratically elected ones. "Oligarchs" are too targeted and a big word. And like you said, there are other problems too.
What's why "Fake News" and "Make America Great Again" worked so well. Simple and stupid, an elementary schooler can read it. And have enough ambiguity that they can be interpreted however the listener wants to.
The organization had tried other slogans for their protests, none brought out more people like "No Kings". Give people what they want I guess.
I think the same gatekeepy gamers that make fun of people just playing NHL or CoD are the same snobby people who make fun of casual players that just like to play match 3 games. Let people have fun.
FC is literally like 75% of EA's income. I wish they took more risks with stable income like this. The problem is the large amount of people they keep hiring are product managers with business degrees. Stangleholding the creatives who love games with conservative business strategy and market research.
