It’s a TRAP. Google is hosting that spreadsheet. Do you want Google to know about your income/assets?
Even if you copy the spreadsheet it is still hosted on Google with all the code. Do you know what is behind the code of the spreadsheet?
Google or Forbes is not your friend. They put that out there to collect data.
Not a problem. I put about 50 different values in just to see various results all the way from 10,0000 to 100 million. That data does them no good whatsoever. I imagine many others are doing the same.
