I couldn’t even name a alternative solution besides teamspeak 😅 And team speak was dead for years, no idea how their reboot is currently doing. But even if there are better and free solutions, people use what’s convenient to them. There is zero reason for the billion WhatsApp users to not switch to signal, still most of them never even think about switching.

I’m one of them lol. Hate discord but there is no choice if i wanna play with friends.
