while I agree with the sentiment in general, I think it's safe to say that people have been giving up their darkest secrets to google and social media companies for many years.

Some people feel there is nothing they can do about it. Many people do not know / understand just how much they can know about people, so seeing it that way, yes it can be surprising to see so many giving the data right on the screen; as opposed to giving data passively / not understanding the value of combining or that they are even collecting passive data like location or what you type and delete, or what you hover / keep on screen..

I don't have hope that there will be any laws stopping the collecting and combining of data by any of these companies.

I do like the idea of an every year reminder sent to users showing what they can see with the data that has been collected and stored.

That is doable, and possible to get people to change some of what they share if the portals are honest in what they collect and how it can be combined with other data to paint more intimate / detailed pictures of you and those connected to you in some way.
