> pointless, lazy, selective, quoting that willfully misconstrues what's being quoted

They quoted the part they were replying to. The point was to show what they were asking about. If your question pertains to only a part of the text, it only makes sense to be selective. That's not wilfully misconstruing anything; that’s communicating in a clear, easy-to-follow way. The context is still right up there for reading, for anyone who needs to review it.

> the answer to this question is incredibly clear: for the developer that created this tool

Questions aren’t only ever asked out of pure curiosity; sometimes they’re asked to make the other person give them more consideration. The question you quote was accompanied by an explanation of how the commenter found the approach less simple for them as a user, suggesting that perhaps they think the developer would have done better to consider that a higher priority. (I might add that you, too, chose to selectively omit this context from your quoting—which I personally don’t see as problematic on its own, but the context does require consideration, too.)

> if that makes you unhappy enough to malign them then maybe you should just not use it?

The author of the extension chose to share what they made for others to use. They asked for feedback on user experience and expressed doubt about their design decisions. If someone finds they might not want to use it because of what they consider fundamentally flawed design, why couldn’t they tell the author? It’s not like they were rude or accused them of any wrong-doing (other than possibly making poor design choices).
