no, they don’t
Please be careful with your claims.
In my experience, whenever investigating these claims and refutations we usually find when digging past the pop media headlines into the actual academic claims, that noone has proven it’s not happening. If you know of a conclusive study, please link.
Regarding the article you have linked we don’t even need to dig past the article to the actual academic claims.
The very article you linked states quite clearly:
The researchers weren’t comfortable saying for sure that your phone isn’t secretly listening to you in part because there are some scenarios not covered by their study.
(Genuine question, not trying to be snarky) Will you take a moment to reflect on which factors may have contributed to your eagerness to misrepresent the conclusions of the studies cited in your article?
once again, that isn't what they were reported to have said. [and researchers don't need to repeat the basic precepts of the scientific method in every paper they write, so perhaps its worthwhile to note what they were reported to say about that, rather than write it off as a generic 'noone can be 100% certain of anything'] it's a bit rich to blame someone for lacking rigor while repeatedly misrepresenting what your own article even says.
what the article actually said is
and even within the subset of scenarios they did study, the article notes various caveats of the study:
there's so much more research to be done on this topic, we're FAR FAR from proving it conclusively (to the standards of modern science, not some mythical scientifically impossible certainty).
presenting to the public that is a proven science, when the state of research afaict has made no such claim is muddying the waters.
if you're as absolutely correct as you claim, why misrepresent whats stated in the sources you cite?
