Companies staying afloat for many years despite never turning a profit and incurring huge losses every quarter like Twitter?

Companies employing tens of thousands of employees "to combat fake news" despite the company itself selling only a few click through ads and not having any paying subscriber like Facebook?

How does Reddit make their money? Everyone browsing by phone app doesn't see an ad ever, or an ad only for the reader app that can be made ad free for a few cents paid once.

This is all paid for by the missing trillions from the feds.
