Thermal mass works pretty much the same with or without a fan but weather or not you have a fan effects temp control drastically an it effects how objects in the incubator effect airflow.
Sorry you have issue with someone being corrected.
I dont really care what you call it but there are hundreds of people on here every day trying to learn. Many of which English is not that native language. Others dont have a background in thermodynamics. Those people will try to look up "heat sink" an get confused because it makes no sense in the context of incubation.. If you use the correct term "Thermal Mass" then it will make sense when they look it up.
