It's the same with messengers, if your friends arent there how useful is that foss messenger really?
This is so difficult. How many people would be willing to switch to Signal or Wickr for one friend? And then what if none of their friends don't want to switch? And then the friends of those people, etc. Trying to switch workgroups, family, friends and all of their friends as well is a lost cause, it would never happen.
Shit like this is why I got a dumb speaker. It just plays audio, it doesn't have a battery (meaning that unplugged = zero power), it doesn't have wifi, it doesn't have an assistant, it just plays the music I ask it to play via Bluetooth.
