According to your link the company actually lost money. So if the fine should be proportional to the company’s profit, the government should be paying Opendoor?
To me it seems more reasonable to set the penalties at a level that’s high enough to deter violations. To make that calculation, the main inputs should be how much money they can make from the violation and how likely they are to get caught. Other profits the company made that weren’t from fraud are irrelevant. (or in this case, losses, since we are discussing an unprofitable company)
Be the first person in a group of founders to want someone to put something controversial down on paper. I guarantee you. You will get chilled out.
You ask if the folks who depend on the company's product should go without. No, they should move their business to a competitor. If there is no competitor, maybe that's evidence that the business plan is not viable while acting lawfully.
