You of all people should understand that criticism is FAR more valuable to growth than compliments. If the various post-mortem business analyses I've read are even moderately correct, stifled alternative points of view from within contributed mightily to EK's eventual downfall. No one wanted to listen to those who warned of approaching problems. I've also heard that same thing right here from various ex-EK employees.
If I show ten people one of my dorky amateur photos and nine of them tell me I'm a genius, those nine will each get a sincere smile and thank you in return. But the tenth person who called me a talentless idiot? THAT person will get as many hours of my undivided attention as he needs to explain to me exactly why he feels that way. And when he finishes the thank you he gets from me will be far, far more meaningful, because his criticism was far, far more valuable to my future growth.
The deal here is to defend the right, and value, of opposing points of view. There is no quicker way to lose your way than to surround yourself with nothing but people who will tell you exactly what you want to hear. Echo chambers can be devastating to one's grasp on reality. (As an aside, that's exactly why I have never, and will never, put anybody here on an ignore list.)
It's not necessary to believe that what the poster said was true for anyone but him. And, in fact, he never claimed to be speaking for anyone but himself.* But I strongly believe it IS crucial for both us and Alaris to hear him out. And others like him. Not emotionally. But analytically.
Think about what he says. Weigh and compare it objectively. Measure it against other opinions received. Decide if it illuminates the situation in ways that perhaps may have been inadvertently overlooked. And then form and carry out a remedial plan of action if one concludes that might be warranted.
But regardless of where his data leads, smile and thank that person for their honest input. It's priceless. Don't gag and threaten him with personal responsibility for destroying the entire industry. Do that, and both you and the companies you support will never improve.
Remember, if all one ever does is succeed, one will never grow. It takes failure to stake out the areas requiring improvement. Without failure, and recognition of it, your limits will never be known to you. And without knowing those limits, it's impossible to formulate a plan to exceed them.
* The poster referred to above uses "I", "my", or "me" no less than 17 times in his short 13 sentence post. I really don't believe he is trying to speak for anyone other than himself.
