You're not alone. I have been doing the same, but not just WhatsApp, also Facebook, Google, Microsoft, Apple.. Any company that abuses it's power to lock down, sell data from or attempt to control their users.
It's often pretty lonely. Ive had friends simply stop talking with me. Ive been left out of weddings, birthdays, etc. I guess it's like trying to be a vegan at a BBQ.
Worst part is that when what Id feared comes true, they just move on to the next worse option and the cycle continues.
