For whatever reason, chat seems to definitely encourage tribalism. The last company I worked for eventually bought into Slack because so many people WOULD NOT use anything else while a lot of us were like "ANOTHER chat app??" because we were perfectly happy with Gchat which we had as part of Google Workplace.

I know there are some historical reasons for non-SMS because of text pricing outside the US but everyone I know in the US would look at you funny if you wanted to use some special app for texting.
