There's good evidence it's not causative. (There are a number of
diseases that cause the body to retain aluminum. sufferers of these
diseases don't have different rates of AZ than normal, for instance.)
There isn't even very good evidence that there's increased aluminum in
the brains of AZ patients, either in the plaques or the brain
generally.
They're saying it in the context of "buy our expensive alternative
because Scary!". That's dishonest, and if they're going to lie about
that (or not care to get the facts straight) about what else are they
going to lie or not bother to get facts straight?

The Romans knew lead was a poison. They knew asbestos caused lung
cancer, too.
There's not a higher rate of AZ in societies that drink lots of tea.
(Tea takes up aluminum, and it's present in relatively large amounts
in the beverage. One would expect a higher AZ rate, were Al a cause.)
