I read about that case, but if I am understanding that correctly, in those messages someone admitted to having an abortion. Having evidence of something happening and not having evidence of something not happening (e.g. a gap in period tracking data) are pretty different in the courtroom. I was specifically asking about subpoenaing period tracking data, citing a gap in the data as evidence of anything. If that held up in court, I would lose any remaining faith that I had in whatever government this happened under, because from a purely logical point of view, lack of data is not evidence of anything.
