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

Was true (except for trustworthy encryption). Then network effects took over and peer pressure did the work.

It could happen again in a good way this time, but the resistance will be stiff.
