Yep. But they have been granted an exception to the rule.
Again, they are the exception to the rule. They are allowed to claim free exercise rights, not because they are corporations, but because they are, by their very nature, religious institutions. That’s how they’ve been treated for years, that it is their religious nature, not their incorporation, that allows them to further the free exercise rights of their members.
You apparently believe it is the corporate form that somehow gives those organizations their free exercise, but it’s not. It’s the religious nature of their creation and members.
If language is a barrier, we could change from “for profit” to “secular” in these distinctions. I have not always been as precise as I could have been.
But to answer your question, there is, to my mind and the mind of the IRS, the Supreme Court, and a great many people, a difference between religion and secular profit making. People, certainly, can be both religious and profit making. Corporations, however, aren’t. If your corporation wants to be religious, be religious. If your corporation wants to be for profit, be for-profit. But combining the two is bad for religion and for the law.
Render unto Ceaser and all that.
