I believe if everyone who was against the current oligarchy started placing guillotine stickers everywhere, like you might for a favorite band, people would feel less isolated in their distaste for the current system.
And in an ideal world those who the guillotines are for might realize just how much they are in the minority.
Not sure if he was 100% the final person guillotined during the French revolution but I’m pretty sure they’re referring to Robespierre. I thought he was pretty well known but idk maybe that’s just because I watched a load of nerdy shit growing up.
