The screenshot in Carbon Black's response clearly says that VirusTotal "makes the binaries available for download to their partners".
And here's the relevant text in the disclaimer:
> You are hereby advised (i) VirusTotal makes the metadata publicly available along with scan results from dozens of anti-virus products and (ii) VirusTotal also makes the files available to VirusTotal partners. You must determine whether to elect to enable this feature at your sole discretion.
And the warning also has this text in bold:
> If you have custom business applications with confidential business information on your network, sharing binaries with VirusTotal may not be appropriate for you.
With this being optional and off by default, I think it's on the customer to read the clear warning presented and make the call that's right for them.
