TL;DR: Global passives give too much power blah blah... Riot hates free stats.
Janna and Zilean will definitely get completely new passives because they are terrible for themselves only. TF's is basically the same except it has a chance to give more gold, and of course it's now for him only.
They don't like passive game play - the fact that something is there and gives free stuff. The Bulkwark was to deal with AoE heavy teams but in the end, it's just a good item (which I recall being nerfed once and I could see again if they're that hard against it)... apparently.
They like temporary AoE buffs though (ex: Jarvan's flag) because it involves more skill though?
I honestly don't like their reasoning why they like temporary stuff and not auras (at least, that's what I'm getting from the thread).... but hey, that's just me.
