While PhD theses are typically quite straight forward, i.e. at many (most) universities a PhD needs to be a proper publication often with an associated IBAN and with a copyright licence assigned to the University (or at least a number of hard copies given to the University library), masters and bachelor theses differ considerably. Often the copyright fully belongs to the students, they are not required to be published (often even are not supposed to be, as they were done at some industry partner, or results have not been published in journals yet due to time constraints...). So it's legally not that easy for universities to publish or even archive them especially in retrospect.
