Permissions for Notion were simultaneously consolidated and disbursed as per that proposal you posted @Sprinklesforwinners. In essence Notion permissions were decentralized to each DAO org unit to manage themselves. The alternative was the chaos of everyone being able to edit everything (including a hacker who changed the multisig addy). It was pretty brutal.
Personally I think the Notion works decently for the whole DAO now, but if you want to change it, can’t you write a proposal for that rather than shut down the DAO?
