Mine isn't either.
I use a local VLAN so once it's set up it's moved inside the VLAN and only accessible within the house.
The cooker hood and hob communicate over WiFi... put a pot on the hob and turn it on and it automatically turns on the hood fan and lighting. 5 minutes after removing the last pot from the hood and the light goes off, the fan slows but continues to extract at a lower speed for a little bit longer before turning off.
It's pretty damn useful, and if I want to update all of the software and firmware I just reconnect the VLAN to the internet. If I remotely want to access things, my phone VPNs into my house and sees the VLAN.

I've managed to live my entire life without having my cooker hood on the internet.
