No this nitpicking is people wanting to know the specs of something they might buy. What most people on HN probably think of as e-paper is not the same as and LCD tech.
Part of the problem is there's some use of e-paper to mean "e-ink but we don't want to trigger their trademark lawyers" polluting the space. (The part of the description that actually made sense to me was where it said "same display tech as in Pebble!" ... which is pretty neat, and not-at-all-eink...)
