That's a good point. The best way not to know about any successful attacks is not to know about any of them. I also can definitively state that I'm not aware of any successful attacks, but for obvious reasons this is a basically meaningless statement. Without more data, it's not clear how meaningful the statement they gave is, and while it probably is more meaningful than mine, it doesn't make sense to jump from what they said to "there have definitively been no successful attacks" based on it.
> No, their statement says nothing about attack attempts.
Exactly, they're keeping the statement brief and correct. They have sent multiple batches of notifications to users on previous attacks.
The statement is clear, covers their primary use case for the product, and I'm sure is legally sound. You're grasping at straws trying to think up ways they can be lying to you. I would be very surprised if you ever have used their lockdown mode with any actual cause.
It is advisable to not grasp at straws to think up ways that highly paid lawyers are not saying exactly the words they have approved. That is literally their job and they are good at it.
If they meant something more expansive they can do so. It is not the public’s job to do it for them while letting them retreat to the legally binding interpretation at their pleasure.
