I was so pleasantly surprised when my Microsoft / Harman Kardon "smart" speaker (Invoke) issued a firmware update upgrading it to act as a simple Bluetooth speaker. It's wildly more useful now!
Google has done this with the Stadia controller, and also recently open sourced the firmware for the Pebble smartwatch. They may discontinue a lot of stuff but their track record for discontinued hardware is pretty decent IMO.
