tl:dr; fill your comment with (often meaningless) things just to make the person you're giving the feedback feel better.
(I'm all for being polite and framing negative feedback positively, I try it myself, but ultimately it's all completely pointless. If someone can't take "I don't like that you did x, it should be why because z" without it starting with "I really love this and I love what you're trying to achieve ... but I guess you made that choice for a reason, so keep up the good work!" they might need to rethink creating things... someone shouldn't need to say they care and say they respect the person: if someone is giving you feedback then it's already clear they care... but then I guess that's the human brain, we're weird creatures that constantly need positive reinforcement)
People often leave comments that are poorly worded, poorly thought of and sometimes completely irrelevant, all to make their voice heard and not because they care. There's too many of those here on HN
