I doubt their motivation was "now we want to be evil". Probably more like "evil isn't actually well defined and people keep pointing to this and having dumb arguments about it".
That doesn't sound like a typical corporate thought process. There is plenty of cognitive dissonance around logos and mottos and whatnot by corporations, and unless it affects the bottom line, they won't do anything about it.
While it can easily be criticised in encouraging black and white patterns, people that have an intellectual problem with the definitions are mostly smartasses and very often actually do "evil" shit, as defined as self-serving to the disadvantages of all others.
