It's simple, really. The only reason the Morse testing was required was
because of the international agreement that code is needed for HF access.
Now that the world agrees that code is no longer required for HF access
(from the WRC-03), there is no reason to keep it as a licensing requirement.
All of the emotional arguments about "tradition" and "keeping the riff-raff
out of the hobby" are irrelevant. Anyone who wants to use code will still
learn it, and the mode will still continue to be used by amateurs (who are
really the only people still using it). Every country should drop the
testing requirement, including Canada and the US because it simply is no
longer needed, and the whole world agrees, except for a bunch of stubborn
old hams (and no one even cares what they think any more).
