To be fair, this is due to the horrible branding on NginX's part. Nearly every non-technical person I know has pronounced it njinks, because using 'n' phonetically as 'en' is not exactly commonplace.

Watching our PM get to their name in a story and pause for a few seconds and just say "that word" instead should give you some idea of how counter-intuitive it is.

You don't have to work hard to parse good branding.
