Email, docs, music, maps etc have reasonable alternatives and you don’t depend on others to switch (a gmail user will receive my email from tuta). But with WhatsApp either you conceal and use it or you just don’t talk to people (tried convincing them to switch to signal and it simply doesn’t happen)
How do you deal with it?
Never used it. I have app fatigue. I am forced to download so many apps, make so many accounts, I really dont want to make another one. Sucks to hear how few options some countries have. The people who matter wont care how you want to keep in touch.
