In theory, VC's, investors, and founders are considered to be "sophisticated" investors. However, they deposited a significant portion or all of their money in what was essentially a regional bank that experienced a sudden surge in deposits over the past two years. They put their money there because it offered better terms. When it went belly up they wanted to be made "whole" again. They put money in without understanding the risks.
On the other hand, as the article says, lots of these bonds were bought by Asian banks for their wealthy clients who were looking for better returns and considered these bonds safe. Who in theory sound like a similar demographic as the VCs and founders. But the comments here go on about how the investors need to lose everything.
The contrast in commentary is fascinating.
Maybe these are all just indicators that the financial market has become way too complicated with risks hidden away and no one is really able to wrap their head around all the risks. This complexity might actually be a good thing for everyone. With the central banks bailing out banks/financial instruments It is a case of reap the rewards while the going is good and then once things go bad, just shout about how the risks were not understood and get your money back.
As a side note, I am not personally invested in either of these cases.
