Weird that people argue about this. If the value of a company is being talked about, then stocks is what people generally refer to. Now, if you’d specify and talk about some other value, then sure, but if only “value” is being mentioned I see no reason to think it would mean something else than stocks.
I doubt that’s how the password is used for. More like they copy all contents of the phone and ask the password to go through encryption. The data is already there, accounts don’t matter.
This is also the reason why it’s no good to have a dead man’s switch or the like, as in a certain password just wipes everything. You’d just get arrested for destroying evidence and they continue from a copy.
