You see, the problem is that whatsapp came very early, when it released it wasn’t shit and it provided free messages which in many european countries wasn’t a thing yet, everyone hopped on it and used it as main communication platform, this created a big ass network effect that is nearly unescapeable, even today i can’t escape from it because i am the only idiot who uses Signal and Matrix and no one wants to leave whatsapp because they already have an account and all their contacts
