I don’t see what these points have to do with WhatsApp and co? You can’t take care of them if you don’t install some shitty app they decided to use? And they won’t listen to you if you don’t use the same app? Age is no sign of competence. One should listen to the one more competent in discussed matter. No matter the age or whatever else attribute.

Besides…it’s not really just “a small amount of privacy”. You’re on Lemmy, so I just assume you somehow know better.
