I think the abortion and trans kids situations are putting into sharp relief the danger of large third parties knowing too much about us. Facebook is absolutely scanning its servers for signs of unwanted pregnancies and relaying that information to red state law enforcement. Other platforms may be doing the same thing.
Women in the US are advised not to use period-tracker apps, given they do often sell the data they glean, and don’t discriminate against far-right interests. And anti-abortion organizations are shopping.
