Is it not technically 'stolen' ?
It's literally not "stolen" because we created a new blockchain, with a new token, and got new listings. No one owned anything before Hive existed and they sure are hell weren't "entitled" to it.
If the tokens that weren't airdropped are "stolen" then the SteemIt stake you used for years was "stolen" from the community. Regardless of if SteemIt delegated it or not, it was "stolen" according to your definition.
