@Smoothound not saying you are wrong but i jumped from Whatsapp years ago to Signal based on principal alone , besides its ties to FB it made promise that your convo's are encrypted and could not be read. fast forward to when lots of Crim's got done and it was found out that this wasn't the case whats the point of using that chat app if its main focus was privacy then it just gets slammed down your throat.
Don't get me started on the strawman argument of "well if you done nothing wrong you got nothing to hide" , there are still levels of privacy afforded to us individuals today that sometimes can come as a challenge for the technically inept but it doesn't mean we should not use them if they are available to us.
Only thing Whatsapp should be used for is sending large pictures/memes/media to another person for sake of business transactions or keeping "social" and just using it as the "common app" everyone uses for sake of basic communication.
Hope i didn't derail any chat i was just adding my 2c
