I'm not sure how I feel about all of these companies shutting down prematurely to return investor capital (the following example is not based on this company, but it illustrates the point). If a $50M investment actually means $10M in risk capital, and the $40M will be returned at the slightest sign of failure, then entrepreneurs are giving up far too much equity because the investor is actually only risking $10M. Further, the signal that a $50M investment sends to the market about a company is far different than that of a $10M investment.
Combine that with other things like preferred shares, and these large investments wind up being horrible for entrepreneurs, unjustly rewarding for the primary investors who are actually risking small sums in exchange for large portions of equity, and unfair for others that invest based upon what the "smart money" invested with a huge headline number.
