I just want to take this opportunity to thank "adtech" and everyone working in it for making local storage way more complex than it otherwise needed to be because you couldn't/can't stop yourselves from abusing users.
This is a good example of how the discourse on this subject seems to have twisted itself around. No one serious ever thought "advertising" was a bad thing, not really. It was the potential abuse of the stored data people were worried about. But that's hard to explain, especially without good examples to which to point[1]. So fast forward a few years and... now it's "adtech" that's the enemy in isolation. That seems u…
Here's an ongoing example that should get someone put in jail:
Pharmaceutical companies target ads for addictive drugs at the people that are most likely to become addicted to those drugs.
(For the victim of this that I know personally, it wasn't painkillers. As far as I know, there have been no repercussions for the manufacturer of the drug in question or the ad networks.)
