Different thing though. Things like this feed the myth that facebook is always listening to you. It's close enough to the idea to allow the cognitive leap from 'possible' to 'happening' without more than anecdotal evidence. I've never seen conclusive proof, e.g. showing data collection, transmission or usage, that any targeted advertising is based on overheard conversations whilst a phone not in use. Targeted advertising is just really good at segmenting people, combined with confirmation bias and the number of ads people don't register mentally until they are relevant in this context.
