Thank you Ana for great explanation. I have seen some discussions about it here previously but yours does help. I might tried to look into it in near future.
However it is not about me. It is about thousands and thousands members here who will not stumble to this thread or read this post about new privacy issue. So no, it is not really their choice. They might be just not aware or if aware just still having no idea how to do it. It would be much simpler to do it for whole software, whole site in one go. Simple basic restrictions for outsiders.
