I think that Hoff is suggesting that creating value is better than blaming. As an entrepreneur I seek to create value, this enables me to make a profit. Adjusting my business to changed circumstances is a requirement for survival.
If you're looking to assign blame, then do evaluate your own particular motivations. You have probably already made or you are now about to make a mistake; you've taken your eye off your particular goals of creating value for your customers.
Certainly don't repeat (unprofitable) mistakes. Do learn from your own mistakes, and do particularly learn from the mistakes of others.
Competing against an organization that seeks to place blame on others? Now that's a potential business opportunity. That individual or that organization is not competing effectively. They're dissipating their competitive efforts. They're potentially vulnerable. Do you have a wedge here? An opening? Use it.
Do continue to move toward where the target business will be, regardless. Whatever goal or profit here you might view as your motivation. Blame doesn't move you toward that goal.
I agree with Hoff that creating value is better than blaming. OTOH an occasional rant might make us all feel a little better while we're creating all that value. :-)
