It's not unsubstantive in my opinion. It's just an expression of my opinion, which is questioning the thought of making no difference of personal and business goals combined with an emotional component (sadness).
This reply is already more substantive than a mere "That's sad", which may or may not have any thought behind it. If you fleshed it out a bit more into a thoughtful point, you'd have a good HN comment.
Merely stating an opinion doesn't count as substantive. There needs to be something to interest the reader.
