First, even though the title of this thread does not specify the model S, it is in the forum section devoted to the model S. It is not in the forum section for the model 3, charging, etc., so a normal person would conclude that this thread is directed to the model S.
Second, anyone that owns a 85 kWh battery (either the regular model S or the P85 variant) payed a significant upgrade charge for that battery. The “standard” battery at that time was the 60 kWh battery (disregarding the extremely limited availability of the 40 kWh that was actually a software capped 60 kWh battery) and if IRC, the 85 kWh battery was about a $10,000 upgrade charge. I would venture a guess that almost everyone that paid this upgrade charge did so for the increased range available from the 85 kWh battery. So this thread is perfectly correct in discussing the “taking” of range that we paid for.
Third (and most importantly), please stop confusing degradation with capping. Your discussion keeps referring to degradation. This thread is not directed to degradation. It is directed to limiting (capping) the charge voltage of the cells in the battery to a value of less than 100% SOC (eg, 4.2 volts). I suggest you obtain a copy of the app ScanMyTesla (unfortunately only available for Android phones), an OBDlink scanner and a suitable adapter cable. Plug the cable and scanner into your canbus port and you will see that an uncapped battery charges to 4.2 volts at 100% SOC. A battery that has degradation will still charge to 4.2 volts. However, a capped battery charges to a lesser value (4.09 volts in my capped battery). So please, stop confusing this thread by talking about degradation. They are two completely different, unrelated things.
