This is a loyalty test. If you say SI you gain a loyalty point. If you say AI you lose a loyalty point. The government is forcing you to choose whether you posture yourself to align with the government or against the government.

And like many "loyalty tests", one of the goals is to abuse the cooperators too, forcing them to ritually scar their reputations, impairing their ability to make a new home elsewhere. Sure, you got your "loyalty point", and maybe everyone agrees you had no choice, but you've also gotten a "damaged goods" point from the opposite perspective.

Authoritarians know coercion doesn't demonstrate real loyalty, their real goal is to (A) deprive people of choices and (B) get them to misremember it as their own idea.

Just coincidentally, .si is the Slovenian domain, .si domain registrations skyrocketed and Melania Trump is Slovenian.
