Controlled doesn't mean "I am writing as Grandpa" but rather "I am writing on behalf of Grandpa."
Part of what needs to be addressed is "is what I write and what I control online part of my _identity_ or part of my _intellectual property_?"
No, a person inheriting the estate doesn't have the right to pretend to be Grandpa and collect social security checks or defraud people based on that identity.
Yes, a person inheriting the estate does have the right to take the collected poetry and essays that Grandpa wrote and publishing it. ... even if they are published on Facebook.
Are Facebook, Twitter, Github etc... in the first category or the second category?
Microsoft outlook has a neat feature to "send on behalf of" (account settings, delegate access). Such an approach would be something to consider for an online presence to distinguish who is doing the sending - the deceased or the estate.
> You are essentially advocating that you should be able to inherit the identity of a person
Just because eg the person's wallet is now technical property of the estate, doesn't mean the identity information contained within (driver's license, credit cards, etc) now acts as a form of identity inheritance or transferal. That's not how estates work legally.
