I don't know if they've done that already. But it means they can be around forever, no matter what foolishness they get up to with the remainder of their donations.

If Wikipedia can resist the urge to enshittify longer than anyone else, they've earned it.

Personally I think while wikipedia does rake in an extremely large amount of money via donations, they provide an amazing platform and haven't felt the need to make it shitty with new features - or "keep up with market trends". I'm happy for it to stay this way.
