True, but it might not actually be a bad idea to hire based on an 'easy to hire' technology and actually use a technology that the developers are more experienced in. For example, I've worked in a number of environments that hired for node.js, but where the devs were actually recent RoR converts who were moderately proficient in node.js and its ecosystem. In the case of getting an MVP out quick, it might still be better to use RoR.
