Well SMS/RCS doesn't work with the phone number on my business card either because it's an office landline/voip. So it's no better than the other application you criticize as not being universal enough.
Good messaging systems work. Period. SMS/MMS and RCS often work when your internet doesn't, even on insanely congested networks.
I rather not have the carrier in control, and not have a protocol depending on a phone number which I don't own, rather than have something that will work the 0.001% of the time where my Internet is too congested to send a simple message. Also I don't think RCS works any better as it uses the data connection, unlike SMS.
SMS has many flaws, including not receiving the message if you swapped your SIM card when traveling to another country. The carrier may or may not send you the message when you come back.
Sure. I'm all with you on avoid. That doesn't in any way mean we don't continue to develop them and have them in place so we can use them when needed.
That's my point we pretty much never "need" SMS. RCS was not even worth developing.
