They're not just Canadian values and not really authoritarian. Contest for power is and has always been the primary function of the political. Politics is the business of deciding who orders, the fact that someone does is not in question, and a bunch of peace protesters or truckers had never any meaningful impact on anyone. The internal party politics of whoever is holding power is what matters. That goes for private companies or governments regardless of how often they talk about participation or inclusion or whatever else.
So the actual observation here is that it isn't really relevant whether you're for or against the trucker cause, but and the author seems to agree, the only effect that the trucker protest has is that it makes them look exactly like what they're being caricatured as.
