I dislike live chats but many users and businesses see value in such functionality... who am I (or the author) to demand they stop?

There's a mantra in UX that says: "you are not your users". The way I interpret that mantra is that you shouldn't assume that your opinions, preferences, motivations and behaviors are the same as other users'. In other words, a single experience or use case will never cover 100% of the needs of all users.

Sorry to state the obvious, but different people have different needs, and they see value in different things. To demand that "XYZ" stops because one person doesn't like it is so wrong and myopic... it's actually a pet peeve of mine. It's fine to share your experience "When I open my email, I do XYZ" but for the love of god, never make the sweeping assumption that your experience covers everybody else's' needs or opinions.
