Lois McMaster Bujold, writing science fiction in 1986 about a genetically engineered hermaphrodite used it/its for pronouns (when not using she or he)
I remember reading a goodreads answer later that she would have used they/them if it had been in common enough usage that she had encountered it.
(though in my mind '86 is relatively recent, but maybe I’m just old)
Page 15 of the pdf has this chart

From what I recall they were saving all the packets being broadcast as they drove past. (as opposed to only logging SSIDs)
Edit: Yup, it is as I had thought - but also it was more intentional than I had remembered: https://www.wired.com/2012/05/google-wifi-fcc-investigation/

So if I download an image from the web with GPS data, and then open it in an app that just reads images (so it doesn’t need location permissions)… That app (on some phones) gets a modified version of the file?
Which could make me think that the image doesn’t have location information.
Which could result in me uploading that file using a browser (that does have location permission turned on) to a website, and I think it’s safe to share because there’s no private information in the image, but my phone has conspired to mislead me.
Yes, that is cursed.
