Reading through that article you could probably find/replace with Reddit.
The complaint alleges that Vonage’s officers decided to offer shares to customers because they knew institutional investors who normally buy IPOs would be reluctant to buy Vonage stock. Vonage has consistently lost money and has never been profitable.
Oh, ouch! If this is similar, it’s a bit ironic that they’ve pissed off the people who would’ve been most likely to invest in the IPO.
