I've never understood why top posting is seen as such an evil thing.
What am I missing?

Two reasons:

One, as a thread progresses, a mix of top and bottom posting becomes
confusing when someone wants to look back through the quoted material.
Since most posters to newsgroups bottom post, that is the de facto
standard method. Email users typically top post, so that becomes the
standard for email.

Two, top posters often quote the entire text below their reply without
editing it. That makes the replies longer than they need to be. You
often see a one line "me too" post, followed by several hundred lines of
quote. Bottom posters seem to be more into the habit of quoting only
what is necessary to retain continuity, so it keeps the length of the
posts under control.
