As a matter of fact I even put my finger up to the screen to verify that the edges were not in any way wobbling. The subtracted shape is a gyroid, which in no way has natural axes, so I beg your forgiveness for still not understanding the question.
I meant what I said, that it appeared that you hadn't bothered to read the page, or to fully read the comment. Your question is talking about a sphere (which can, btw, be rotated "off axis"), while the original comment was indicating one of the subtracted spheres from the page. Any of those subtracted spheres could be rotated off axis. So either you were ignoring a pertinent part of the original comment, or hadn't bothered to look at the subjects that comment was directed towards (either of these scenarios would violate HN guidelines).
Off-axis rotation could mean many things in the context of the original comment, as is pointed out by other responses to your first comment. While it's true that a gyroid has no planar natural axes (by design), a gyroid can have many natural axes, depending on the space it is modelled in and the criteria for axis selection. For example, an axis can be found in the radial symmetry about the center of mass of a gyroid, in an infinite number of planes.
A sphere can also be rotated off axis. If the axis of rotation is not projected across the center of mass of the sphere (rotation would be different than the infinite number of natural axes going through center of mass) is one way. Another way would be if the axis of rotation tended toward one of the COM natural axes at both ends, but was non-linear. Another off axis rotation would be if the axis of rotation was the natural axis, but was not co-planar with the rotation of the viewing axis, which would make it appear to wobble.
Was there a need for this attitude (which, by the way, violates HN guidelines)?
I was looking, not unreasonably, at the linked page. I see that indeed the first example on the "Examples" page exhibits this wobble - thanks to user jmiskovic who was actually helpful.
