As I read it, the point of the post is that the student workers are the only ones being inconvenienced and that Anonymous should be targeting the administration directly. In particular, note this part: "Scripts is MIT's largest web host but it's run entirely by student volunteers. Any and all attacks that are supposed to get the attention of the administration are instead being handled by SIPB members." Presumably, the author would feel differently if the ones actually affected were those responsible for Aaron's death, even if the author was personally inconvenienced.
