Your descendants probably. Especially if grandpa earned a lot of dough which by heritage would be theirs now. Or just for the sake of privacy. Would you care if your private social network data was dumped after your death?
To me, when I sign up for confidential that means now and always. Not until death do us part.
Go back three or four generations, and most people can't even remember any of their ancestors names. Why should I care about the privacy of people who died long before I was born, and whose names I can't even remember?

I guess it is a matter of personal preference. But why should I care about what happens to my personal info long after I am dead? Once I am dead, and my children are dead, and their children too, and nobody alive can even remember who I was–what difference does it make to me then? (Maybe 100 years is too short, since a century from now I might still have living grandchildren – but I think the principle is sound whatever the exact timeframe should be.)
Given modern data storage paradigms, with perfect[0] recording of a wide range of data, it's entirely possible that people might care in the future. For example, if you have an ancestor who was near-sighted, you are automatically disqualified from any colonization missions (regardless of your own eyesight) due to the presence of potentially-flawed genes.
It would be similar in concept, if not degree, to the Nuremburg Laws[1], which were only made possible by the meticulous record-keeping of the pre-WW2 German bureaucracy. Whether or not those records are used for malicious, distasteful, or nefarious purposes at some indeterminate future is not something we can control or predict effectively today.

I don't find the future you describe very plausible. Keep in mind that you only inherit (on average) half of each parent's genes, a quarter of each grandparent's, an eighth of each great grandparent – so even if your great grandpa had some nasty health problems, odds are you didn't inherit whatever genes might have been responsible for them. Also, don't you think by then, our knowledge of human genetics will likely have advanced to the point that we don't need to assume you might have bad genes because your ancestors had health issues, we actually have a complete sequence of your individual genome, along with a much better understanding than we have today of what all those individual genes do?
So while you may be comfortably dead your descendants may pay the penalty in unexpected ways. A suitable time frame would probably be beyond centuries but rather like today finding Neanderthals (prehistoric men).
This is all apart from the breach of contract in a social sense.
no?
