John Woolman was a Quaker who counselled other Quakers not to keep Negroes. If you read the wikipedia page, there's no hint that Woolman was concerned about slave owners.

That's not a concern for the fate of the slave. That's a concern for the fate of the slave owner.
Similarly, I do not believe that subsidies are good for the recipient. Everyone knows that when you build a cost structure into the operation of a business, it's extremely hard to reduce those costs should business conditions change.
