Am I the only one who likes this change?
I'm tired of explaining to my relatives why they can send their picture to one person but not to another, or why it requires wifi for some contacts. Mixing two incompatible messaging standards communicating via two different channels in one app is confusing for many people. Sure, it also has advantages and I think you could make it work, but the app actively asking users to make it the default SMS app is not a great idea.
