Plaintiffs in the lawsuit claimed that they were shown ads for Air Jordan shoes and Olive Garden after ‌Siri‌ recorded them speaking privately about those companies.

so basically this is just confirmation bias or frequency illusion with no actual evidence whatsoever. What are the odds that someone who talks about Jordans or Olive Garden is shown a targeted ad from literally any other data from their online presence? or even a complete coincidence entirely? Of course that's going to happen amongst the millions and millions of iPhone users on a day to day basis.
