This list looks like it includes for-profit only. Also, with the church, it's "company" status is relegated on a per-country basis, usually to gain non-profit taxation benefits. So it's a little murky there.
That list doesn't include states, which are pretty wealthy. And I'd say you should include states as much as churches in the comparison, because the Catholic Church, at least, is historically much more akin to a state or empire than to a business. (I think your argument could apply to the more recently formed churches.)
As for your video link, that's about televangelism, which is extremely recent. Even Tetzel wasn't really in it for his own personal profit.
