Yes, and the influence of logical positivism underpinned the Copenhagenist interpretation of QM, which as I understand it is still the orthodox, mainstream interpretation taught in schools and colleges. Except that neither logical positivism, nor the Copenhagenist solipsism are adequate for the purpose of understanding and describing the universe in which we live.
I suspect you have misunderstood Feynman btw, or taken the quote so far out of context that it’s meaning is lost. Physics needs metaphysics, if it is to perform the function ascribed to it by Einstein, Hawking, and others, to offer a full description of the natural world. Feynman, to whom is attributed the ironic admonition to quantum physicists to “shut up and calculate”, was as aware as anyone, that multiple competing efforts to interpret, rather than simply apply, quantum theory, required of both philosophy and science a quantum leap forward in human understanding. We stand on the brink of that leap leap forward today; QM has given us the iPhone and the H-Bomb, but in terms of what it may tell us about the fundamental nature of our reality, we are still finding our way in the dark. This, I suspect, was what Feynman (always a ready source of handy aphorisms) was referring to in the comment you quote; he may have been lamenting, as Hawking did, that the philosophers were so far behind the theoretical physicists, who were exploring calculus so complex that only a handful of mathematicians could keep pace.
This is not to say that physics doesn’t need philosophy; this is simply to say, that the philosophy of science has some catching up to do. Read Helgoland by Carlo Rovelli, and you will see that ground is being made in that direction, and that the artificial compartmentalisation of science, philosophy, and mathematics, alien to the likes of Socrates, Euclid, Plato, Pythagoras etc, is a barrier to the spirit of enquiry.
