This is the danger when our lives become increasingly dependent on digital middlemen who are not regulated as utilities, where legislation has not caught up, who can proudly declare themselves "just a private company you have no say" and use nebulous ToS violations to shut people down.

When people violate actual law, we know which specific sentence in the written law was violated. We have a chance to defend ourselves. We have (supposedly) impartial judges and juries to help determine the truth.

Tech companies are building parallel institutions for judgment and execution, but building it for themselves and they have no plans to let their users have any say or transparency. It's a digital version of "rule of men" rather than "rule of law" -- "you're condemned because I, the King, say so."

This will continue until external powers (regulation) force the quasi-digital-fiefdoms to open up. Hemming and hawing about "gee, this is kinda harsh" won't have an effect on them.

The lack of an appeals process seems like the norm, sadly enough. Maybe, if there's enough of a backlash, they'll restore accounts for people who don't currently access from sanctioned countries.
