If unsatisfied customers disappear, is there still a problem?

from here

Thanks to Naomi Wu for working so hard to raise awareness of what is clearly a serious issue, and shame on Signal for not doing more to educate users on the safety considerations of using their app.

In theory, secure messaging is meant to protect those who might otherwise be in danger if the contents of their messages were found out. If at-risk Signal users are getting disappeared under normal usage conditions then the question has to be asked whether Signal is fit for purpose.
