To maintain a clear separation between for-profit and non-profit activities. If a non-profit operates in a market with for-profit competitors, tax authorities may start considering it a for-profit organization, making all of its income taxable.

And maybe to allow choosing the right people for the right job. If the non-profit has an ideological purpose, its leadership should probably reflect that. At the same time, the for-profit subsidiary probably works better under professional management.
