Agreed. Also, I expect that malicious elisp is relatively rare, while malicious js is probably about half of it.
While I'm trying to sober up people who are panicking I don't mean to downplay the dangers. The op article is quite informative and should be read by all emacs users. While malicious el code is probably rare, the value gained by compromising an emacs user (programmers academics researchers etc) compared to compromising a random js user (everyone) is probably way greater. Also very few people look at emacs security
