Lawrence,
The SMS standard has been around as long as CTIA, and I was there at the beginning.
Last I looked, CTIA wants to lock in customers as much as the next Joe, so if a functionality called "Reply and copy" was asked for by customers with messaging, why would they say "no". SMS has changed massively since the beginning, and why not more? Why not this functionality?
The problem with CTIA is that they know squat about "customers" and customers do not even know who they are. You know who knows customers? Apple.
If Apple can get the gloves off and fight the CIA and FBI, supposedly to protect customers, Apple can surely take on CTIA with good odds. Google would likely join in (assuming their Android phones do not already have "Reply and copy").
My problem with you two guys is you only "salute" Apple with "Apple knows best". Is it best to not offer what neither of you has denied would be a big improvement, per my example?
Perhaps folks like you two apologist are what is preventing Apple from doing better.
