The Deployed option, as you may have surmised, had absolutely nothing to do with 
whether or not your sliders work.  And, in fact, Deployed has no impact on 
slider functionality at all.

But sliders can be disabled by setting Enabled->False.  This is a useful 
feature, as it allows a continuous display of controls, but temporarily 
disabling them in cases where the controls are irrelevant.  This is quite common 
in user interfaces generally, and there's nothing strange about how Mathematica 
does it.

What is strange is why you should have had to set Enabled->True explicitly. To 
understand that, I'd have to see the code.  Enabled is set to True by default, 
and unless you've somehow changed the default settings, it should not be 
necessary to explicitly set it to True.

In general, the Deployed option makes an output act more like an interface and 
less like a raw bit of output.  This means, for example,

* Random bits of static text are not selectable or editable.  In most interfaces 
(imagine a dialog box in any program you used), you can't go about selecting
bits of text and rewriting them unless that text is inside of a control like an 
input field.

* Graphics are not editable.  You can't double-click to get inside them. You 
can't select them and resize them.  You can't take take 3D graphics and spin
them around.  The graphics, like the text, are part of the background.

* All controls remain active.  There are, in fact, other options you could have 
used to achieve the above effects, but those other options would have messed
with the controls, as well.  By using Deployed->True (or the Deploy[] function, 
which basically sets Deployed->True), you get controls that work as they should 
while everything else remains a fully inert part of the background.
