It’s the “don’t start something you won’t finish” argument. Maybe in a department someone makes a podcast, the novelty wears off, three years later nothing else has happened. Visitors looking at that department see out of date material. Bad.

Problem is, it’s hard to predict what’s going to work and what’s not without trying it. That’s the point about evolution and change (though there’s also a need to commit to supporting something new like this). The question then becomes: who is going to monitor which departments haven’t posted anything new, and remove old material. The housekeeping could become an additional workload. Then people think perhaps it’s simpler to have everything “closed” so because that reduces the severity of the risk…
