The motivation/justification from the author why they believe removing lisp but adding Electron somehow sums up to being "lightweight"? Maybe the author thought of the UX/baggage/legacy or something else when they thought about "lightweight", rather than how much memory/cpu cycles something is using? Not sure, but maybe there is a more charitable reading of it out there.
