Is Views restricted to using only Default Input Format for Display of Node/Fields?

I have an Activity Stream (Twitter) Block which displays hyperlinks within tweets correctly. However, when I make a view of the stream and create a block-display, the links disappear. When I change my default Input Format to be permissive to links this problem goes away. This absolutely cannot be a daily solution however, because the client insists that the default format forbid link-based XSS. What I would like to do is set the Input Format within the main view display to using something other than the default. Am I misunderstanding the problem here? What I have done: I have changed the default formats for the Activity Stream content type...no effect. This is not surprising, because the problem only shows up in the view anyway. Does the Views module automatically defer to the Input Format settings of any nodes it makes into a collection? That being the case -- would I have to shift this issue over to Activity Stream to ask about the Views integration?
