I would like to know more about the Signal issue too.
If these issues are that much of a concern, then perhaps they could be brought up. Privacy Guides seems transparent about the discussions they have behind their decisions, unless I am mistaken.
See this thread where objections over the new feature and the security issues surrounding it were mostly ignored (they did allow pins longer than 4 digits, but they continued to call them "pins" which to many users is a 4 digit number): https://community.signalusers.org/t/proper-secure-value-secu...
At this point, I consider the fact that the very first sentence of Signal's privacy policy has been a lie since 2020 to be a dead canary. I suspect that the folks at Signal have been telling people their service cannot be trusted as loudly as they can.
Perhaps that'd also explain why they've made some other odd choices like removing the ability to use Signal for both secure messages and plain old SMS/MMS and adding cryptocurrency features.
