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?
The advantage is comfort and numbness. Even if it is considered to be a negative advantage by any tech savvy mind - or any other reasonable and logical person. My point is to not whine around like OP. Either use it and get fucked or don’t use it and have a good life.
