Facebook had a rough 2018 and 2019 didn’t really start too well either, when Instagram leaked passwords. Meanwhile, Amazon’s Alexa had it’s own scandal when it turned out that not machines but humans listened to their customers commands. With all of this combined, it doesn’t sound like a great idea to offer more surface for these kind of events. Still, Facebook seems to plan to release a voice assistant of its own.
There’s no indication that it will extend outside Facebook’s own hardware—yet.
