Charging money does not make something a corporation. Though I'm aware of the financialised nature of some American churches, I'm talking from a British perspective where that isn't the case (as far as I am aware, I don't personally attend church).
Either way, I don't think there's as much moral hazard if you're charging someone at cost as part of a communal service, compared to trying to squeeze as much profit as possible out of grieving families.
