You're doing business with a corporation - it's a legal person after all. There are reporting requirements etc so you can check all you need about that corporation very precisely. You don't need to know the owners at all. It's not like you can know with US/EU corps - go check and see how many paper trails end in Virgin Islands numbered corporations ;-)
That's your opinion, and fortunately not one that nearly anyone shares.
You're doing a common Internet Thing by twisting a conversation into the topic you actually want to talk about, even though it's wholly unrelated.
Just because something bad happened to your family doesn't mean the entire planet should adjust fundamental aspects of how humans interact. That's just your trauma speaking, and not a rational thought.
Regardless of opinions, you can't know the owners of many corporations today. Are you sure you're not doing business with businesses that have owners hidden behind Virgin Islands numbered shares? I wouldn't be, it's actually very common. And if you're actually doing business with them - where's the problem?
