And who's fault is this? I'd love to see you arguing with a police officer or a judge with that reasoning...

The airdrop was not to be "fair" to everybody, it was done to create a way out for SPR investors by getting a head start with HLM.
And it is great for HLM too, since it will start with a lot of coins in circulation - great for some market stability.

It was also seen by speculators (aka traders) as an easy way to gain profit. Also a reason for them to keep SPR at bittrex.
At many occasions (for months) it was strongly recommended to put all your funds in a wallet. You didn't know? Again - who's fault is that?
