Can someone explain what this actually means?

The developers added that since there are (almost) no “undo” buttons in the world of crypto, the user’s LINK tokens are now stuck in a non-upgradeable—and thus immutable—GHST staking contract forever.

What is a GHST staking contract, and why can't the other party in the contract simply refund the tokens in a second transaction?
