Perhaps you never heard of the psychological targeting done for political purposes through the misuse of mass data. (Cambridge Analytics)

Edit: to be clear, people in the comments have already provided many examples of situations where corporations/governing bodies have misused specific people's personal data (zoom employees watching webcams without knowledge), however I also don't think it makes sense to brush off the impact of mass data available as a result of much of the population freely giving away their personal data.

Yep, that always seemed to be the reasoning, even if downloading the Signal app takes no more than 15 seconds to download and start using.

Though I definitely get not wanting to juggle 3 or 4 chat platforms.

Got a surprising amount of contacts to move into signal from Whatsapp, though the iMessage gang can't stop iMessaging.

As an android user, I don't see why you would want to use something that restricts your secure messaging to a single platform.

As a result of Signal's poor decision to stop SMS service, I frequently forget to check my SMS app for messages.
