I've never read these comments as user-hostile. The distro saying we won't touch these
settings isn't telling you they don't care, it's saying that it doesn't seem like something we
should do. Maybe if they find the magic number that everybody loves this won't be a problem.
Right now they have the people with dying laptop hard drives screaming at them. If they tweak
the number, maybe it will silence those people but anger some other user? Maybe the number
they pick will be wrong and instantly kill the hard drive? The right answer isn't clear, which
is why they're falling back on, "We won't touch it unless you explicitly tell it to."
