I cannot reveal more right now...
Yes, you could have revealed more but you didn't/where not allowed to
Anyway,
fact is that every device (especially the ones that connect to other devices and such) need to be protected.
Protection is not just about the OS, but also about applications, data transfer (connection) and such.
Do you need locks on the doors/windows in your house?
No you don't, but unfortunately there are people who don't respect your properties.
Better safe than sorry
