I think you make an important point that needs to be realized. MIT, like many other large institutions, is not a single entity, but a collection of many people. While many people have expressed their disappointment with MIT, along with statements such as "How could the university that hired rtm do this to swartz", we have to see that MIT is a big place with many people running different parts of it! While disappointment towards MIT and sadness over Swartz's death is certainly understandable/warranted, we should wait for Abelson's report before we heap scorn, jump to conclusions, and find something to throw on the stake.
When good things happen in "collections of many people", the leaders and the institution take plenty of credit. When bad things happen, the same should apply. And more so, really.
The university is a big place, but that doesn't mean that we can't heap scorn on things they have apparently done.
Of course leadership always bears responsibility to some degree, but remember the MIT you think of when there is great research going on (the professors, researching students, etc.) is also generally the MIT that is supportive of hacker culture, OCW, open access to the buildings, etc.
