No, the reason is legal. Everything, and I mean everything else is secondary. They can tell in court that they did everything what they could. Of course:

- it’s a lie

- not even a white lie, they know perfectly well, that they can do way more

- most of the security “features” are completely useless

- they also know this

However, it’s very difficult to prove these, and laymen don’t and won’t understand the details.
