David Sobotta, a former director of Apple's federal sales group, has criticized current CEO Tim Cook's lack of leadership skills, as well as being "lightweight" in terms of understanding technology.
Sobotta, who published a Kindle book pertaining to his 20-year experience at Apple called "The Pomme Company" (Pomme being French for apple) spoke about Steve Jobs' successor in an interview.
When asked for his thoughts of the recent firing of iOS chief Scott Forstall, which was purportedly due to his lack of apology for Apple's abysmal iOS maps app, and retail chief John Brownell, Sobotta said: "Tim will react to the numbers or his fear of being wrong quickly. Fear of being wrong is a managerial trait that runs strong and deep in Apple because of the way Steve ran the company. Even the appearance of being wrong when in the end you might be right is dreaded at Apple."
"Technology-wise, I think Tim Cook is a lightweight," he added. "I never felt passion for technology from Tim like I did from Steve and some of the great engineers."
Sobotta has previously been critical of Apple in a number of areas on his blog, Applepeels. The titles to some recent posts are "Do Apple Employees Need A Witness Protection Program?", "Has Apple lost its soul?" and "Will Apple Ever Figure Out the Cloud?"
