I mean, sometimes I put up an OOO because I’m on vacation and not checking email. Sometimes I put one up because I’m travelling for work and will only have sporadic access to my laptop, but might get to check once or twice a day. In my role, it’s important to make that distinction. Maybe it’s not so important for other people.
I don’t think a lot of people working there made a habit of doing that, which is why a lot of people felt the no external OOO policy was excessive.
