There's a reference that may be related to this in the book "Hackers: Heroes of the Computer Revolution" that talks about how Stallman despised passwords and worked to promote more open access to the systems.
RMS has said multiple times that technology doesn't change our values, because our values are far too ingrained in order to be changed as something as trivial technology. But different technologies change the outcomes that we judge using our values. The proliferation of the internet and data sharing changes whether or not passwords are a good thing (since they are now used to protect user data from other people, rather than block users from accessing a system they should have the rights to access).
