Yes you're missing something.  Theres a big difference between these
two:
	1)  giving card blanc to _everything_ from vendor A because you trust
vendor A
		and auto-installing it on every PC so configured
	2)  accepting a single plugin from vendor A upon explicit actions

I think that the idea of having the software producer sign the network
downloadable thing
(plugin/java/activeX) is a good idea.  But trusting it takes more than
just a reliable vendor.
I might not want everything produced by the vendor.  The last time I
read the ActiveX docs, that's how they appear to read -- is that still
correct?   In my mind Java wins big for security because it 
will soon support signed applets _and_ encapsulation.
