I’d love to use Signal exclusively and recommend it or move over group chats wherever possible. But some friends and family keep me on WhatsApp and messenger. IMHO using those less is better than using them a lot and having more apps is better than socially isolating yourself.
I’m starting to get the data hoarding crowd more and more. We have been taught this dream of “the internet never forgets” but people missed to mention that it’s on the average Janes and Joes to make sure that is the case. Corporations want the internet to forget because it’s better for business.
