I see a lot of pessimism in the comments. But I think this is a great step in the right direction. Other companies should take note. More of this, please!
I think you can spot when your phone has been hacked, for example the mobile phone carriers can spot the traffic and slow down the communication making it obvious things are not working properly. Take using the AirBnB app, you put in a criteria, the results come back then the spooky hackers wipe the results and give you a list of their "safehouse" Airbnb locations meaning all you can do is book into one of their safe houses. The fact you see the AirBnB results get wiped and then slowly other results not really matching your criteria appearing should tell you, you could be booking into a safe house.
Dating apps/websites is another way to get into a relationship with "undercover" investigators and I dont think most people are aware that any crime ever committed since birth can be prosecuted so as no one can predict what legislation might be hitting the books in the future, it might be hard to keep your nose clean.
I think most people are aware of dodgy text messages which tends to be the start of malware entering your phone.
