Unless the company is money laundering or doing something else illegal - can you think of one realistic scenario where someone goes to work everyday and has no idea how their company makes money?

I'd return the bits if the tech and inbox was there. Not sure that's what you intended there.

If it is not a company’s business model to let you try before you buy and has a return policy that is unacceptable - then don’t buy their product. You wouldn’t shoplift it would you?
