The GP did indeed seem to be arguing it's default-bad (though I note you didn't go off at them for this). The reply has said nothing about it being default-good: only that it's not necessarily default-bad. You're assuming a black-and-white binary & by extension you're seeing arguments that weren't made.

There's nothing bad faith about the commenters post & assuming the role of a moderator in a discussion you're inventing phantom arguments in isn't doing you any favours.
