It is true, but not really a factor in real-life use. Most trainer apps have a PowerMatch feature. The KICKR is unique in that it can directly pair the trainer to a power meter. Personally, I prefer the control of being able to turn it on or off from my trainer program, but you could make that invisible with the KICKR. I have had both a KICKR and have a Neo. Here is my quick decision tree between the two:

• The Neo feels great, it may be smoother and more natural than the KICKR
• The Neo is huge, ungainly, and difficult to carry; as bulky, 50 lbs. objects go, the KICKR is relatively easy to carry around
  
• The glowing LED under the Neo is really cool
  
• I like that you do not need to block the front wheel with a KICKR
• The slight sway the Neo allows is a huge feel upgrade; supposedly the new feet on the KICKR allow some movement as well
  
• My Neo reads about 20W lower than my Assioma pedals at high freewheel speeds; they are improving it with firmware, but the KICKR is more consistent across all flywheel speeds
  
• The Neo works without power, which is super cool
• I am a TrainerRoad guy, so I will never experience the Neo's other slick features like downhill coasting simulation and road surface simulation
• The 2T supposedly fixed the virtual tire slip thing that plagued earlier models
