Not the case. What's happening here is Windows is removing the ext4 partition completely, expanding the ntfs partition and writing to all of it.
Windows update did that to my <1 year old laptop. I figured it had just wiped out grub, but when it was booted from a live-usb there was no ext4 partition there at all. This has been reported many times.
Microsoft should be sued for this shit. Legal protection from destroying people's data that is not part of Windows or in a Windows partition, whether deliberately or by negligence, is not something that can be legitimately covered by a license agreement.
Zigbee does work with a generic controller on Home Assistant and other platforms, and there are >3100 devices that are compatible with zigbee2mqtt, a Zigbee to MQTT bridge that exists to bypass the need for proprietary Zigbee bridges. No proprietary app or Internet access required either, but it was not easy to set up. Here's a list of supported devices: https://www.zigbee2mqtt.io/supported-devices/
