TLDR - I believe with DW at least, the principles, particularly "being a fan of the characters", conflict with springing the absolute maximum adversity I can imagine (which is a pretty high level of adversity) and which is allowable w/in the fiction on them.
This is exactly what I mean, though.
Make the move that follows means you can't just swing for the fences, you can't be the "adversity firehose" described, you have to think about what follows. You don't pull the punch but you also don't go for the hardest hit you can think of, you go for the one that complies with "follows" and "fan".
It sounds like in BitD the principles and "Desperate" thing make this a bit different.
I don't know if anyone is saying it must be "absolute maximum adversity at all times!" so much as saying that you don't need to pull punches. To stick with the boxing metaphor, some of your punches may be jabs, and others may be haymakers....but whatever kind of punch it may be, let it fly. If you establish that a PC is at risk of a haymaker, and then the roll calls for a hard move, you hit them with the haymaker.
I don't think that's at all contradictory with being a fan of the characters.
BitD does differ a bit in that I think the players have more ability to resist horrible consequences. I don't shy away from really debilitating or even fatal harm when the dice call for it because the player has an option to Resist Harm to reduce its effect at the cost of some stress (meaning that Level 4 Harm which is Fatal simply becomes Level 3 Harm, which incapacitates), or they may have gear (armor) or special abilities that allow them to mitigate it, or they may have both (which would make Level 4 Harm become Level 2, which means they're still on their feet, but may find some actions more difficult).
I've only played DW on a few occasions, so I'm not nearly as familair with the playbooks and abilities as I am with BitD, but I don't think that DW has quite the same level of control in this area on the players' part; though I could of course be wrong. It's been a while.
