A concept of "influence" without any information transfer is
ambiguous. The meaning of this "influence" will be dependent
on the particular interpretation used, it has no operational
meaning.

Communicating is not the same as influencing, communicating means
transferring Shannon style information and entanglement can't do
that faster than light. But it will still let you influence things
faster than light. Quantum entanglement can influence things
faster than light but you need more than that to transmit
information, you need a standard to measure that change against,
and Quantum Mechanics can't provide that standard; all it can do
is change one apparently random state to another apparently random
state.
You and I have quantum entangledcoins, I'm on Earth and you're in
the Andromeda Galaxy 2 million light years away. I flip my
coin 100 times and record my sequences of heads and tails and then
just one hour later you do the same thing.
It doesn't work like that. You need to generate the coins at one
location, then bring them separately (at sub C speeds) from the
location they were created to Earth and Andromeda. It's because of
this that FTL is not not needed under QM to explain EPR.
Bell's theorem rules out this "common cause" explanation. Such an
explanation would be a local hidden variable account, and that is ruled
out. Claiming that Bell's theorem doesn't apply to many-worlds doesn't
work either. I think that any "common cause" explanation would have to
contend with the Kochen-Specker theorem -- which also rules out any such
hidden variables.
