Videos are inherently large. There are better compression algorithms than what phone cameras generate by default, but video reencoding is slow, and the results still too large for "covert data channels".
Normal players would have noticed the bandwidth and CPU usage, and volunteers have already agreed to data sharing, so there's no point in keeping secrets. Same as claims that the Facebook app listens to people talk: someone would have caught it by now.
Also, AR capture was never very popular, mostly a gimmick for new players. The game was already a battery and power hog even without it.
Why videos though? Photogrammetry is about still images. You don't need ALL angles of a target from a single user. Other users pile the needed data up, guided by their own pokemon locations.
and photogrammetry from crowd-sourced disparate still images was the biggest, flashiest "public" display of the technology: https://www.ted.com/talks/blaise_aguera_y_arcas_how_photosyn...
Good point, maybe that could be done. But that's not what TFA is about, so you're not vindicated yet.
Yeah and for niantic to achieve good photogrammetry with their random collection of photos taken from different angles, on different days, etc they would need some kind of ground truth to train on, which is implausible. You'd need to collect a parallel dataset of high-quality videos for traditional photogrammetry and .. hang on.
