There is a bit more nuance here though. There may be users who trust their old systems but no longer trust the current state of its manufacturer or their binary only updates. Proprietary blobs go against the core freedom as defined by FSF so I can understand why they block by default but IMO they should allow informed users to override. Simply censoring without allowing a user to bypass is not user (or freedom) respecting. The power to choose should be with the user, whom the FSF claims to represent.
