If you would read the article, you would understand the point you’re missing.
No one recognized them because they were public figures. In this case it’s not clear how they were recognized, but in the general sense, it is clear that social media will gleefully dox randos using technology like facial recognition. Attractive security guards, people dancing, etc. Just yesterday, someone took a picture of me at the pool just for walking with messy hair.
The point the article is making is that anybody can be made a public figure now, because of technology.
They could have identified me, that’s the point.
We couldn’t identify the criminals because that example was before facial recognition.
You read the article but you still don’t get it.
