How does a team plagiarize its own work? please explain this logic to me.

The COVID name received blowback because it was not a smart move. However, it doesn't take much to realize that the premise of Kickstarter on the blockchain is very worthy and a great use case for the technology. Every time you invest in a project you are not given any guarantees that it will work or that the coins you hold entitle you to anything in return.

If the project was rebranded UllU, while keeping the same dynamic and dev team I dont see how the accusations you are raising any sense. Perhaps it would be good on the dev's side to buy any covid coins remaining for an equivalence in ULLU, but even that is beyond of what token holders are entitled to.
