Temporary halts don't count, it needs to look like mana won't be withdrawble for at least a few months in order for this to resolve YES. This market is about the intention to cease donations, not actual functionality on the site. (So an announcement of "we'll stop in 2024" will resolve this YES, while an announcement of "we're putting it on hold for a few weeks in December but will re-enable in January" resolves NO.)

If they remove the charity option but begin allowing mana to be exchanged in return for items of value that can themselves be sent to charity relativly easily (such as a currency), that will not be sufficient to resolve this to YES.
