That's a really weak argument.

If I was a Lawyer, Cybersec employee, or any other person that needed pressing information alongside security, your "unreliable argument" might be compelling.

However since I am using Session to speak with normal people in which our conversations are not imperative to receive notifications of, availability is not a big loss.

Are you joking?

Why would I bother with security if what I was communicating was so unimportant that I don't care about availability?
