I guess that depends on definition. At yahoo the ability to use a product for spam is a vulnerability. If a spammer can email a link to yahoo.com/something/random which redirects them to mypharamasite.com then it's a vulnerability because the site allowing the redirects helps trick the end user into buying vicodin :).
I can't imagine why javascript redirects add much value in a blog post. But everyone picks a different spot between features and security - and that's okay by me.

There are a lot of people that have used blogspot as their host for a long time, but then decide to get their own domain and don't want to lose their readers. That's the motivation I've heard for allowing redirects in the past, though I don't know what the current policy is.
Blogspot is a lot more like a hosting service than an application in terms of what it allows, probably because it's one of the oldest.
