Right, but another way of looking at it is that you might not suffer from the same sensitivity to motion as the author's wife.
My point is that this isn't an aesthetic choice where your opinion is as good as mine - they are reporting an actual problem that they are having with the software.
For you it's just an animation, for people who are actually sick by looking at it it's a software update that just made their device unusable if it can't be turned off permanently.
I agree about the setting, I just don’t think one way of feeling about the animations is more valid than another.
