This is certainly my position (and, from the looks of it, Tetrasodium's as well.)
I need to be able to make informed decisions, at least up to a reasonable limit of being informed. Part of that means having a good idea of what I can and can't do. If the rules are ever-shifting, if literally all cases are corner cases and I cannot know whether this corner case will work out like the previous, or form a new and unexpected precedent, or be a one-off solution that should be ignored. This makes making informed decisions extremely difficult, if not impossible. As a result, I will approach every situation with extreme caution--I can never be sure, so I have to be ready for everything to go pear-shaped because this time the DM rules that fire spells actually can't set anything on fire unless the spell explicitly says so, or some other such thing. My desire to improvise or pursue stunts or the like will dry right up.
The "freedom" of rulings becomes a prison of uncertainty. And given that error (or worse, failure) has an uncomfortably high likelihood of taking away my character permanently, and a near-certainty of at least causing problems that my fellow players will have to clear up...well, better to always play it safe then. Rely only on those things I can absolutely trust, never deviate from the path, never experiment. Far from opening the whole world, this "freedom" chains me much more tightly than any rules could ever do.
While I can appreciate your own consistency, the prevalence of the term was more my focus. "Rules lawyer(ing)" is a widely-used term, and I haven't seen major pushback against it or people (obviously not you) saying "it's just used for ragging on a particular style."
