a TL;DR from my own interpretation:
- Dave (the person making the video) feels uncomfortable; 'even talking to my wife on the phone somehow feels stilted, remote, and disconnected'
- Dave talks about other reasons, like struggling to initiate or accept a phone call, that people with ASD might dislike phone calls
- Dave also struggles with figuring out who is supposed to be talking / whose turn it is, especially due to a lack of cues that can be used to identify that
- Another thing mentioned is how the fact that these cues are missing can also lead to misunderstandings. When someone asks a question and expects an immediate response (e.g "I think that..."), if you take a moment to reply the other end might think you disagree with them.
- He also talks about many cues that can imply different things explicitly, like volume, pitch or tone of voice, as well as pauses, pacing or changes in intonation.
Edit: whoops I left a bulletpoint dangling there
That doesn't quite work in the case of Signal
The only data that they have, based on transparency reports and dissections of their source code, is the time you created your account and last connected to the servers.
Messages themselves are essentially only relayed, with sealed sender, and anything that would be actually useful to identify who was at a protest and who wasn't encrypted.
Things like, e.g when messages arrive at the server would have to be monitored live on compromised servers, which reasonably unless you assume* it is wiretapped already prior to a protest, isn't realistic.
*: of course, I am saying this because making an assumption and portraying it as truth (e.g assuming something is already wiretapped based on no evidence at all) is not the smartest of moves when it comes to threat modeling...especially if you wanna stay sane whilst having a threat model
