From an article in The Economist:
“Big tobacco” is what the bosses of several large technology firms have started calling Facebook in private and in public. The company has spent the past year fending off critics who claim it is addictive, bad for democracy and overdue for a regulatory reckoning. Being compared to the tobacco giants is one of the business world’s more toxic insults, but it is not the only unflattering analogy circulating. A lower blow is the suggestion that Facebook may become like Yahoo, the once high-flying internet firm that plunged.
