Investors don't obviously have access to better numbers. Investors in privately held companies generally receive a very carefully groomed set of data. We hope the people compiling that information don't go out of their way to hide anything (although that happens). And we hope that the raw data is accurate (although this too is often distorted). But they probably don't go out of their way to dig up negative stuff. Smart investors definitely don't take a company's offered financials as their only source of information.

And WeWork intends to go public, possibly soon. Those people definitely don't have access to better numbers right now. And they might not get any. IPOs are carefully stage managed.
