>That's a very negative way of saying "that's not my personal behavioral preference"
In my experience, Stockholm syndrome is not used to describe personal behavioral preferences, but rather (unexpected) transitions between such preferences from the negative to the positive.
In the grandparent's own words:
>>> i was shocked by that at first too. Then I came to love it.
Stockholm syndrome refers is a victim forming emotional bonding with his or her captor. Which would mean in instances like this, where the "captor" is a voluntary choice of language, the term is used akin to "masochism" (albeit without the sexual element). In essence, saying "the pleasure from use feature x is derived from the pain of using feature x".
Which is why I commented that "Stockholm syndrome" is a needlessly colourful way if saying "I disagree".
