Not only do I think that that's not obvious, I think its a nonsensical conclusion that really only makes sense as a general statement if you think “for profit” means “to earn revenue” rather than “to return money to an interested party”
and invert the parent/subsidiary relationship.
Obviously, the for profit subsidiary ooerates for profit—and where its not a wholly owned subsidiary, it may return some profit to investors that aren't the charity—but neither the subsidiary nor the outside investors getbthe benefits of charity status.
