Well ... I think it depends on your definition of distortion. One can
argue that, if the RF envelope does not exactly equal the original AF
envelope, the signal has been distorted and that is certainly the case
when the dynamic range has been reduced with compression. It doesn't
increase the occupied bandwidth however [at least not by much].
Clipping mows down the peaks, leaving sharp "edges" or signal
transitions which do increase the occupied bandwidth.

Don't confuse compression and clipping. Compression reduces dynamic range
while clipping sets a hard ceiling and does generate distortion. Compression
used correctly does not generate distortion.

Nothing when it is done correctly on a mode that can stand the distortion. I
personally won't use it on digital modes as my rigs tend to turn it off by

And what exactly is the problem with compression? It's used all over the

It’s a protection system. Over use of ALC acts like compression. No?
