I’m not sure I believe your assertion that the companies in question “pay taxes.” If you operate at a loss you get to deduct that loss. And there are lots of loopholes every company used to avoid paying their fair share. Unless you mean the employer share of the payroll taxes, which are paid on behalf of each employee and in my opinion don’t count.

The fact is that it’s really important to do due diligence on any institution that you’re putting more than six figures into. I would expect any “sophisticated investor” to understand the risks to the degree that they would be able to make an informed decision.
