It is certainly easier to reverse-engineer, I guess.

It still damages your freedom.
I thought twice about appending `*SCNR*' to the previous sentence as it
was first meant as a satirical response in the RMS style. You write up
arguments and all you get back is a totally generic, ignoring everything
you said, `this is bad[tm] for freedom[tm]'.
But after thinking more about it, yes, this should really be _your_
argument, too.
I really don't think it makes more harm compared to a nasty .elc because
Emacs has so much of its core accessible through Lisp.
And then, practically, it does not matter which way you damage freedom,
right?
As a user, you won't even realize the difference:
apt-get install some-nonfree-emacs-extension
Whether this is a shared library that loads into Emacs, a precompiled
.elc that loads into Emacs or an .el wrapper and a non-free executable.
And all the user sees is this, in either case:
(require 'nonfree-extension)
(non-free-extension-mode 1)
And what I also consider important: you can modify every variable or
function binding from the Lisp side. That means that you don't need to
go to the C level to be really harmful. You can also just rebind every
core symbol and already modify Emacs' behaviour quite severely.
Save the old binding, rebind it and you have total control over
everything the user does. You can decide whether you want to allow
garbage collection at the moment by rebinding GARBAGE-COLLECT and decide
according to the phase of the moon whether you pass on to #<subr
garbage-collect> or ignore the request. I really wonder what you could
NOT do.
Emacs is already so powerful that I don't understand all the fuzz about
the shared library loader. It would be nothing more than convenience.
But don't see it introducing any extra danger at all.
I probably repeat myself, sorry.

That's probably it.
