What objection to logical positivism is based on ethics

Accusation of inconsistency; in the fundamental principles, in fact, propositions that are not empirically verifiable and equally obviously not tautological.

Logical positivism is a general philosophical position, also called logical empiricism or neopositivism, developed by members of the Vienna Circle based on traditional empirical thinking and the development of modern logic. Logical positivism restricted knowledge to science and used verificationism to reject metaphysics not as false, but as meaningless. The importance of science has led prominent logical positivists to study the scientific method and explore the logic of confirmation theory.
