That's not right.  You don't need to trust your network provider at
all.  That's a core tenet of Internet security: "you give your packets
to the attacker to deliver."

You might trust them to deliver some packets.  But to say that is the
same as trusting them with the details of a banking session would be a
gross oversimplification of the concept of trust.

p.s., When I said split UA, there are two things: one is the line that
ekr has been following, which is that you are trusting a single
vendor, which is the most important from a security analysis
perspective.  The other is pure functionality: your browser is not
complete without the network side component.  In some of these cases,
the code that sits on the device is potentially unable to function
without the server piece.
