Disclaimer: I own one of these Lenovo devices.

This makes perfect sense, thank you. The last thing Google wants is to be blamed for allowing some old device's camera to be compromised and be the source of a leaked video of somebody dancing naked in their kitchen.

Basically a case of a device company riding some trend 5 years ago installing an OS that has an end date for support and since the manufacturer already got it's money for the device there is no motivation to solve the problem.

At this point why does anyone expect any electronic to be relevant after 2 years of ownership anyway?
