I don't think 37signals is necessarily complaining about founders selling out, of course they have the right to cash out if they can. The condolences are for the industry as a whole. It's about the loss of potentially revolutionary innovation being swallowed up by the Borg. Events like the loss of Dopplr are bad for everyone in the world except maybe the sellers and the acquirer. No matter what Facebook does I will always admire Zuckerberg for not taking the early money and running, and now he's changing the world. Some people have the balls others want that mojito.
