The Apple ecosystem itself is innovative and I don't think there's a single company that does it better.
They still lead in interfaces (biometrics...FaceID) and multi-touch gestures.
I don't use Siri, but I'm glad they are developing that technology in a way that doesn't flat-out violate the privacy of their users. I just hope all the criticism comparing Siri versus Google Assistant and Cortana don't push them to change that posture.
It feels like Apple hate is becoming a meme. You can certainly criticize the company... their product line is becoming confusing, but to say they "used" to be an innovator is ignorant.
