Re: So, once again instead of being about messages, it's about more ads???
I've never regarded SMS as a 'chat' program.
It's an email-lite program - no attachments, plain text, asynchronous.
And like you, I am happy with the asynchronous nature of SMS. If I want to 'chat' with someone I'll use an actual chat program or voice/video communication (whether it be an app or an actual telephone call).
If RCS will effectively be just another chat app on the phone that follows a more widely accepted common standard - and I can disable/whitelist it - great.
If it replaces SMS, it needs to be able to be configured as an asynchronous messaging system, otherwise I just won't use it.
