@doctalk I already listened your dsound audio. In my opinion, Facebook is necessary to general people. Because it is easier to interact with relatives and friends. And I totally agree with you. There is some security issue. Which should be corrected on behalf of Facebook. Because there are some people who want to be careful to keep their information secret. But the Facebook's business policy are not caring at all of them. And as a result, many people are leaving the platform or being discouraged. I think that these policies should be changed soon.
