I can see both sides. Sometimes you have to look at the primary end user of the system, equipment, or device. Some user's skill sets will allow them to take full advantage of the operating window you built and use it to improve, while others will crash and burn over and over again, not because they don't care or aren't trying, but the fact that the simply don't understand the system enough to make good decisions on how or what to change. I'm a firm believer in the more adjustments you can design out of a system, the more effective it will be for the mass majority of operators. In the end, if skiers are putting up big scores on the ski and that in-turn leads to increased demand and sales, chalk it up as a win for engineering and marketing.
I hope my next ski comes with an optional cup holder.
