It’s cool p2p protocol but nowdays no good clients, most of them unmaintained and qtox have so shit code.Feels like developer didn’t learn anything about writing safe c++ code.On android there trifa app but it’s works… pretty weird,there also atox but it’s doesn’t implemented feature about video/voice calls.
Same thing here my grandparents and some other old age people which i know using linux mint.I installed it to their pc 5 years ago and up to date,it’s works fine for them before on windows it was nighmare while they were catching ads malware while browsing the net.
