The list was not made by a person. It was made by deciding on criteria (supporting centralizing the chain) and then running a script. No one went through the resulting list and decided to add or remove subjectively.
There will be an opportunity for appeal on the Hive blockchain using its equivalent of SPS. Corresponding tokens have been reserved in the DAO account for this.
The opportunity for appeal is a good thing!
How, when and by whom will it be managed, @smooth?
Obviously it is early so this is still getting sorted out but one way or another there either be one big proposal to make additional airdrops or a bunch of smaller ones. Whatever is approved by the stakeholders will be implemented in the next hard fork (there are some code changes that are needed and couldn't be done in time for the original fork as well, so this shouldn't take too long).
I would imagine it will be a topic of discussion both on chain or off chain where many will express their views on it.
