I know I am in a minority, but I do not trust #Signal service. I talked about Signal in comparison to several other messaging platforms in my HOPE 2022 talk. The content is still relevant and very little has changed. Starts around the 28:45 mark.
@JRepin @niboe Where did this English version come from? I found the article. https://niboe.info/whatsapp-telegram-signal-privacidad/
For completion, here is the 2021 article I based that slide of mine on:

@thomzane Could also find only this webpage you linked and could not find the source of the original English image. Sorry. I'm almost sure I got it from their website. In cases like this I do miss the Nepomuk integration into KDE which among other things added the source URL of all the downloads to file metadata :)
