Over the past month there have been several airdrops to bitcoin holders based on snapshots of bitcoin's blockchain. Stellar Lumens had an airdrop Byteball had an airdrop and there are many more, let alone bitcoin forks. These are all very valuable for holders, and people that own their private key. There are several problems for exchanges, and it doesn't make sense for them to bake that kind of functionality in until a legal framework forces them too. In which case, yes the customer SHOULD sue, thats the only way to progress this. But the old adage is that if you don't control your private keys you don't have any control. And unless the exchanges start providing access to these airdrops as if they are dividends for holding, then it will be a very complex issue for them.
