I don't understand the question. 1) Why does my data have to be unencrypted by third parties eventually? Most of my data is for me. 2) When I actively decide to give people data, why do we propose they are so untrustworthy as to sell it to a data broker? I am very confident none of my friends are actively selling the data I give them to anyone. 3) Even if one of them did, they would only have access to the data they were given, not all of my data I have ever given to everyone else.
