Both evil and rude, but with
the additional connotation that the rudeness was due to malice
rather than incompetence. Thus, for example: Microsoft's Windows
NT is evil because it's a competent implementation of a bad
design; it's rude because it's gratuitously incompatible with
Unix in places where compatibility would have been as easy and
effective to do; but it's evil and rude because the
incompatibilities are apparently there not to fix design bugs in
Unix but rather to lock hapless customers and developers into the
Microsoft way. Hackish evil and rude is close to the
mainstream sense of `evil'.
