Now that the privacy pendulum is swinging the other way I'm curious if Apple will ultimately be the undoing of this thing they helped create. If devices using iOS 13 start broadcasting a constantly changing bluetooth ID as a part of the new "Find My" feature these systems won't be able to track users from beacon to beacon or know how long you were in range of a single beacon.
This will probably wreak havoc on traffic counters and other infrastructure that use bluetooth bacons to do things like monitor highway congestion and foot traffic
"Another example is Stranger Things and some cereal brand."
Obviously a less than successful product placement. /s
Pretty sure it was the Eggo waffle thing you are referring to. IMO they did a pretty decent job integrating that plot-wise.
Like it or not productions cost money and the people who pay those bills will always look for a way to share the load. If you don't like it prepare for $40/month Netflix.
