Yeah same here! But I think google is trying to monopolize RCS at the moment and there are really no good alternatives especially here in the United States that people are willing to use because its just attached to a phone number and you don’t have to think about it.
BTW you can control systemd and how fast it chooses SIGKILL after sending SIGTERM. I don’t know why people complain so much about it. It’s really just there such that things on your computer end properly without any sort of data corruption or something bad going on after a reboot or the next time you turn on your computer.
