When this was initially announced I saw multiple people posting on Twitter how the the non-Musk version of the company would also occasionally take over short name accounts and give them to government officials and large corporations.
Some of the replies when @x and @music got transferred were also complaining about not being compensated monetarily, which honestly seems like a bizarre expectation. Elon paid $44 billion for the company already. Paying people for their accounts sets up a poor precedent if they decide to take over other accounts in the future, and determining the amount to pay seems arbitrary. However, maybe giving these people a free Blue subscription for some number of years, or even for life, would've been a good move since it encourages them to continue participating on the platform.
