I just read they decided to default it to off. They should remove it entirely imo, but with this move, it costs IT departments $0 and 0 hours of their time to worry about.
I think business + government + education usage is more important for them than personal, and as long as this costs them nothing, I doubt it makes a dent in anyone’s plans. Could have been an apocalypse if defaulted to on though.
I’m glad they’re adding support, but I also feel like this is a hard one to sell to the general public. If it creates a better experience, word will get around about it, but going on stage and talking at length about how there’s a new messaging protocol would have been a challenge for non-technical viewers
