I'm wanting RCS messaging but from the info I've found RCS passes through G servers no matter what and you have to get the G messages app. I'm sure G can see everything that passes through their servers and I don't like that. But apparently SMS isn't as secure? I'm not sure if I want my texts readable to anyone who wants to listen or if I want them readable by G. Should I give in to get RCS or just stick with SMS? Are my concerns valid?
