Its misleading because intel nodes at a given nm is a denser process. Finfet tech nm on its own is already a misleading number. Intels 10nm for example is a denser node than TSMCs 7nm. All companies use a non traditional method of measuring nm (as if they did, how does it make sense that a intel 10nm product have higher density than something that is "7nm") as chip transitior is traditionally defined by the distance between transistor to transistor. And denser = transistors are closer together.

Basically intel is changing its name because its competition more or less did so, because the actual transistor distance in a traditional definition is incorrect, because finfet on its own folds over and the manufacture considers the folding technique to be a transistor when in reality its more complicated then that.

An adjacent comparison would be like treating physical cores and threads the same on a processor the same, or considering AMDs definition of a "core" during buldozer and piledriver to be the same as a traditional core (when in reality it isnt, because although there were 8 integer cores in an "8 core" processor, each pair shared one fpu) so it would challenge the definition. All fabs basically challenged the definition of what "nm" means, and theres no longer a standard to what it really means because they have all abandondoned the traditional naming scheme
