Same as EoS, network effects can be a component of a flywheel, but aren't necessarily equivalent to the entire flywheel itself. Network effects simply mean that the value of the service increases the more people who use it, whereas a flywheel represents the entire positive feedback loop that may be driven by individual components like network effects, EoS, etc. Marketers know very well what network effects and economies of scale are, and the concept of a flywheel is distinct from either. You can have a flywheel without EoS or network effects, and you can have EoS or network effects without having a flywheel. Also, it's somewhat pointless to debate what the "original" meaning of flywheel is. Language evolves and changes, and people from one field borrow terminology from others when creating helpful analogies. Terms like "funnel" and "flywheel" are hardly the first to receive such treatment, and they won't be the last.
