I stopped reading right here.  In the end, this is a minor argument about a
relatively obscure technology issue.  Couching it in moral or ethical
terms cheapens the argument and is a pretty good indicator that the writer
lacks perspective.  Take this as preachy if you like, but there are things
out there that really deserve to be called evil, and this isn't one of them.
