Keep small scale open source alive. F-Droid ftw! And consider to donate to Daniel as developer of XMPP software. See also :
Here is some important context you need to understand Quicksy:
· It’s not successful at all. The user count has stagnated at just under 1,500 for years.
· It’s very expensive to run. While Quicksy doesn’t have that many users it has a good amount of registrations. Sending SMS is really expensive. There are months in which I’m paying ~100 Euro for server cost + SMS. I receive a few donations that reference Quicksy alongside Conversations but nothing close to 100 Euro / month.
TL;DR
Google hallucinated Conversations would upload users Contact lists. Even though the App is fully FOSS and contact permission is pretty widespread.
They removed that permission and now its back on there.
