The word "sorry" does not appear in this post. Instead of apologizing to investors, users, and employees for letting all of them down the CEO writes a contentless self-aggrandizing post.
The CEO also doesn't bother to thank anyone despite being literally and metaphorically indebted to investors, users, and employees for getting as far as they did. [Update: there was "gratitude" - my mistake; sorry]
Besides the self-aggrandizing "we did it first" tone of the whole post, here are a few more parts I'd love to see future farewell posts skip:
> it’s often the pioneers who end up with arrows in their backs
Unless your point is that you were a company who tried to take what wasn't yours and was punished for it... this phrase is awkward-at-best.
> I called these “Friends of ClusterHQ” by the sobriquet “FoCkers”
The use of "sobriquet" doesn't make your adolescent play on words classy.
> The big successes are literally impossible without the many failures. Take a moment to think about that.
What a ridiculous thing to tell your audience that includes employees looking for jobs, investors out of money, and users without a service they may have depended on. Out of those 3 groups only investors care about such things. The other 2 groups are collateral damage to your hubris.
