Grandparent is making the case that it shouldn't have this role, which is independent of it having the role. It seems contrary to "the hacker spirit" to use the is-ought fallacy to discourage innovation. Is it wrong to have a contrary, if probably doomed to fail, stance to the mainstream? But of course a contrary idea would fail if everyone seeks the mainstream instead of it. To justify sticking to the mainstream, you have to weigh its costs against the benefits of the alternative too.
