Amazing advice. Chatwise, I used session, but security-wise, it’s pretty bad and it’s still pretty new and not well-known. I decided to go on with a matrix client called fluffy chat.
As for device, that’s a great idea, which I havent thought about. I could use a portable touchscreen Thinkpad X200T for just everyday portable computing and as for at home, I’ll figure it out one step at a time.
To clarify my original reply to this more, I thought you were just comparing chat platforms in general and not considering if it was libre or not. Again, total misunderstanding from my side.
