Well, not really, considering that Friis and Zennstrom sold it to ebay at a very high valuation and then managed to get paid again when they found out they missed a bunch of core tech.
If they had ipo'd a decade earlier they might not have made as much as they did.
I think it's more that the people on the eBay side were either morons or in breach of their own fiduciary duty to eBay shareholders. The deal terms were voluntarily accepted by eBay; terms which were insane. Plus of course the total lack of any strategic value for eBay. It was the worst tech M&A of its size.
I agree with the general sentiment there, but calling them 'crooks' is a step too far, they've been this side of the law or they would have been sued for sure.
