Being able to track both the name of who bought it and the location of someone using a device like this has got to be a near classic example of private information that hurts no one but could severely damage a person if it got out.
The headline is about them getting locked on, because that's funny, but the buried lead is actually this:
> The security researchers said they discovered a way to fool the server into disclosing the registered name of each device owner, among other personal details, as well as the co-ordinates of every location from where the app had been used.
That's some really sensitive info, with the potential to destroy some lives, or be used as blackmail material.
(I think this is a bigger problem in America than Europe.)
In either case, indeed, we need privacy (because other countries have terrible persecution around matters of mere sexuality) and as much maturity as we can muster when discussing it. I'm so proud of how mature this comment section is. Not a single giggling sexual joke in sight - at least here up at the top. Other sites would be riddled with it, with nothing serious discussed.
This could end way really, really badly; it is even more concerning after reading about the recent grinder fiasco with the Egyptian government.
