I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, BusyBox/Linux, or as I’ve recently taken to calling it, BusyBox plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning BusyBox system made useful by the BusyBox corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX…
personally, signal is a lot easier to set up for a family member who doesnt care about privacy. its just a sms replacement basically, just need a phone number (which is also a downside, of course)
this may be due to “spam” (commenting a lot). not sure. it would be helpful if they actually told you the reason. i got banned from commenting for 3 weeks lol.
