I loved WhatsApp when I had to pay for it.

I'd respect Telegram more if I had to pay for it from the start.

3.50€? Seriously, people use more on coffee.

"Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." - Benjamin Franklin

Seriously, at least for westerners, if we cannot pay the same for a secure messaging app as for a coffee then we don't deserve secure messaging.

(That said, I'm in no position to say if this IM app is good or bad, just reflecting on the general idea.)

I never get coffee argument, if I can choose between coffee for 3.5€ or coffee for free in cup plastered with ads I ain't spending the money

plus I don't really spend money on unnecessary things or pleasures, at least not regularly as your typical daily coffee drinker

The argument is that it's an amount many people can and do trivially spend on a whim.
