I hate to put it this way, but most flights are commercial passenger or freight. Only a small amount are private jets, so this really only affects a small number of people. Do you think Mark Zuckerberg would argue in favour of greater privacy for you? I think the effort of making flight data private (and all of the solutions we'd need to find for very important transponder/communications technology) is better spent on other privacy issues first.
