When you are in your late twenties/thirties, having your parents join Facebook is actually great. It allows someone like me, who doesn't actively keep in touch with them, to share my happenings with them as well as stay up to date with theirs. There is nothing I share that I won't want them to view. Agreed that when you are in your teens/early twenties, this is more of an issue which is why Snap etc. are more popular. But once users move to mid twenties/thirties, they go back to Facebook given the type of sharing it enables.
