We’re not.
Huh? You linked me an article where server cost is the lions share of signal operation.
Most users doesn’t even donate 1€ when using free messengers.
How does signal operate then.
They don’t offer ANY “nice-to-have” features
If they don’t have high server costs, unlike the example from the article you brought up, they should hire cheaper software engineers from a different country or scale down development and have a longer runway.
Like I said - them having this problem is probably due to poor planing.
