What did you think was going to happen: do you have a link? The proposal that passed voting outlined how the 2.0 LUNA coins were going to be distributed: but nobody was going to be made whole. Certainly no UST holders were promised their dollar back: the project doesn’t have the $10 billion USD + that would be required.
UST blew up, and UST/aUST holders were wiped out (or they can still sell USTC for about $0.03?). But Terra decided to give out some of the rebooted LUNA coins by airdrop anyways to jumpstart 2.0.
