Wow, you're pretty smart. Nobody has thought of this before, especially not
the authors of said programs.

This sounds vaguely like religion -- you haven't even taken the time to see
how these filters work yet you are decrying them as "evil".
They happen to be the most effective filtering solution at present, and they
definitely beat the "everyone registers their SMTP server" solution that's
currently being pushed in certain technical forums.
Someday this type of software may be rendered ineffective by some new
spammer invention, and at that time it will be easy enough to just turn it
off and use something else.
