Does this affect any fire evacuation procedures? For example, would it be likely that the nearest exit stairwell happens to be the source of the fire? If so, how would that change the plan?

You’re gonna do great :)

Do you know if Windscribe enforces the free plan bandwidth limit server-side if using the wireguard config?

Ah yes, the classic analog hole. Next thing you know, “premium” content will need Premium Certified custom eyes and ears, only for the small installation fee of $59.99/month.

Use -map_metadata -1 to strip all metadata.

It’s unlikely that there’s some identifying information, but you can use ffmpeg (using the “copy” codec to avoid a re-encode) to strip metadata. It’s also theoretically possible for the video to have used some stenography techniques, but that would be much harder and expensive for the video creator/publisher so I doubt that happened.
