Everything is a possible application of causality manip. It isn't necessarily related to that power, though.
I mean, we could change Type 3 to that if everyone prefers, but I see quite a big difference between changing the property of something and changing the nature of the property (i.e. concept) itself. One thing affects the object, the other thing affects the property. The target is different. As said, like the difference between manipulating gravity and changing the nature of gravity itself.
As long as it's separated it probably isn't vastly important what it is listed as, but separated it should be.
Regardless of what we do, Information Manip should probably get different types, yes. Probably at least 2 for information as carriers of knowledge and information as fundamental thing composing the world. 3 if we fuse
data manipulation into it, although it probably is better not to do that since the separate page already exists.
Hmmm... actually not a big friend of that division. The way the types are laid out is basically just Data Manip via Information Manip, Physics Manip via Information Manip, Concept Manip via Information Manip, Mind Manip via Information Manip. If it's just using other powers via information manip I don't think there's a point to the types. In my opinion, it makes more sense to differentiate the types by the different natures of information rather than the different effects one can archieve by warping reality with it.
Also, one of the ideas of expanding info manip with changing properties was exactly that it shouldn't have be concept manip, after all. So should we go for that option in the end, this wouldn't really be ideal.
Gotta disagree with the renaming. As said, we pick our definitions ourself and don't have to care what others have defined the terms as before in that regard. Like we wouldn't change our chi manip page to reflect every view on what chi was ever thought to be. The entire philosophy stuff is not that relevant for us.
As long as the definition on the page is clear there is no confusion, regardless of what it is named. Heck, 99.9% of the readers know nothing of the universals stuff anyway. (And if someone doesn't read the page they're lost anyway)
Obviously, I don't agree on the "it's just scale" thing. It's like saying magic is physics manipulation on a small scale, since magic breaks the laws of physics to make something happen. Sure, magic breaks the laws of physics in some aspect, but it doesn't at any point change the actual nature of physics. You wouldn't say someone can resist physics manipulation due to being able to resist magic.
Similarily, yes, giving a human the properties of a dwarf technically changes which concepts apply to it, but it at no point affects these concepts directly. It doesn't change the nature of "humanity" when it does so. Without a statement, it's questionable whether such a power even directly interacts with concepts in any sense.
It should, at minimum, be considered a lesser type.
