A (very small) few of these are responses to common Newspeak found in the industry. For instance, RMS insists on calling DRM "Digital Restriction Management".

.. A much more evocative and accurate title. You don't put DRM on something to make it more open, you put DRM on something to restrict it. The name itself is inherently weaseley, this inversion actually calls it what it accomplishes. Besides, nothing is lost, since the initialism is more common in everyday usage.

But a great deal of it is just tiresome pedantry.
