This is kind of my take on it. As gross as I find pipe-to-shell installers to be instinctually, I can't really think of any objections I have about them which don't apply to just grabbing a package from MacPorts, save for one: MacPorts gives me a unified interface for listing and uninstalling that software after it's installed that I don't get from ad hoc installers. But in terms of the common complaints like security, it's pretty much the same - it's not like I'm auditing the source or patches of all the software I'm installing via MacPorts either.
