Looks like Dropbox starting popping up recently on the media. Looks like PR push. Maybe preparing for IPO.
Seems roughly comparable to a company that's about to launch, say, a new electric car running a campaign to get people talking about how fun it is to drive electric cars. Other than the clear effort to get coverage from journalists, is there really something nefarious going on here?
So pushing articles on HN and other outlets doesn't qualify I guess?
