If these licenses weren't already well known I might hear "MIT License" and recognize MIT as a well established and prestigious institution and assume the license therefore has some legitimacy. I might also guess that as an academic institution the license won't be focused on protecting commercial interests as much as sharing knowledge, though I couldn't be certain about that. Similarly for the other established institutions. "General Public License" is quite general, but I could guess it's intended for general purpose use rather than a specific project and that it is public rather than private or commercial. But these licenses are already well known so the fact that their names are not terrible explicit is less relevant today. A new license hoping to gain adoption should try and do better but "Blue Oak" is clearly worse. It is also not an institution that seems likely to establish a reputation for things beyond the license, unlike MIT, Mozilla or the EU.
