Susan, There are three points in your post: your school blocking something, an ISP blocking access to certain information and the potential for ISPs to block certain services. I’ll leave you school aside as I have no idea what relationship schools have to anything in the US. But with the latter two I wonder if you see these as different issues. That is, is (1) a putative right of access (or right to deny access) to a given information baring source just the same, in regulatory / legal terms, as (2) access to a service. (1) seems to imply motivations that are related to particular content or sources of content. But I wonder if (2) does. If we take the Jacques Ellul’s line that “Technical development is neither good, bad, nor neutral” then we might argue that these are the same kind of decision, even if they happen to be less particular. But would we; well, you, take that kind of line, or should we regulate differently?
