The FSF as an window moving org is a view I heard expressly presented at their annual members conference a number of years ago. At the time the discussion, I believe, was in the context of the very active "defective by design" campaign, and in response to some views that a more moderate response to DRM (like that taken by other groups like the EFF) might be more effective.
This isn't incompatible with earnestly believing the views. All of us hold principles that exist on a spectrum and can pragmatically decide how we apply them without necessarily compromising them, in order to optimize for progress of certain kinds on certain time-frames with certain costs.
An example of this, RMS's positions have become stronger as free software as matured: IIRC GNU was originally developed on Sun boxes; but RMS would never use an outright proprietary OS today. Early free software system he used had non-free firmware or other blobs, but he advocates strongly against that today. There are a set of strong ideals, sure, but the amount of compromise someone holding them should optimally take depends on the overall state of the world and their position to influence it.
The notion of software freedom as a human rights issue can be quite foreign to people and without someone taking it very seriously some, especially those who have mostly regarded technology as a black box, can too easily dismiss it.
