      Probably because the need of moderation.

      If you host an instance and let people in (even if it’s a limited circle, i.E. your students) you are responsible for moderation. I think that’s something institutions back off currently.

      For an mail server that’s much easier.

          Many Universities already have their own dedicated subreddits that are usually moderated by a mix of faculty, staff, and students. I know of at least one sub moderated in part by the chair oftheh math department, who is as funny as they are savage.

          An above-average level of shitposting goes on, sure, but it’s also a great venue for the school’s online community to engage across organizational boundaries.

        Universities used to have students involved in publishing magazines as journalists, editors etc. This is the evolution. I’m sure a decent sized uni could find or create a student group who can be responsible for moderation under an official administrator.

      Universities have experimented with more private social networks. I remember YikYak back in my uni days. They either don’t have the resource to spin one up or they don’t know about it.

        Might not qualify as a social network, but university hosted IRC servers were a thing once.

      Because of the network effect and content aggregation. With emails you just want to reach a specific person, with public posts you want to reach as many people as possible. But I also think the whole ownership and control problem of centralized social networks wasn’t as apparent as it is now.

      Back in my uni days (1997-01) my uni ran its own Usenet server. Don’t think it carried the alt.binaries, but did have groups specifically for the uni. Sadly only a small handful of people used it.
