Who asked her that question? I didn't hear anything like that from the interviewer.
We, the internet, need a little more back up for your insinuation that she "routinely" makes these mistakes. Or that a mistake was even made in this case.
Also, there are famous people/businesses that use Dropcam, but I would never disclose them as customers because I don't have their explicit permission. Our friends and investors, however, are mostly happy to be named.
Full disclosure, I met Jessica for about 2 minutes at a Dropbox party once. Do you have anything to disclose?
