I think this might partially be a case of different uses of the word ‘burner’ - what they describe is not strong opsec, but it is a way to reduce how much you provide for free (which is often more work for the company to get). By this, I mean not providing so many photos to track your every social visit and movement, not immediately providing life updates (ie, relationships, purchases).

Will meta find out most of this? yes. But I suspect it will be slower, more error prone, and sometimes more costly. Which don’t seem like a bad thing. Is there a good technical term for this? Hardening?

Also, I’ll note that the point of the suggestions is to reduce noise in a persons life, not to go off the grid. I think the blog is trying to be more about curtailing and removing sources of distraction.
