Why doesn’t Signal strip “date taken” metadata from videos while it does from pictures? (lemmy.ml)

Why would it? Ideally signal has no clue what's being transmitted on its network. It doesn't know if those bytes are a gif, a PDF, an mp4, flat pack, apk, anything.

Because stripping files metadata is an expected features for a messaging client. Not for the network like you described but for the client.

I would also heavily assume, that it happens client side before sending the content to Signal servers.

The app knows, they could do the stripping locally before sending, like they already do for video transcoding.
