I also had to learn that lesson painfully when my network connected Brother printer got a (unasked for and unapproved) firmware update that disabled the 3rd party toner cartridge it was using. It's now blocked from the internet in my router, but it's unfortunately a case of shutting the barn door after the cows are gone.
The bridge already has some weird requirements like refusing to work unless you connect an ethernet cable. As far as I know the update is to force you to use an account with the app, but the devices should still be compliant with other controllers.
If you use HomeAssistant and have some Philips Hue equipment, you can pick up a $30 coordinator and you'll be in full control. It's a nice bonus that compatibility with other zigbee devices expands dramatically.
I got rid of my Hue Hub ages ago.
Plus finding I'm logged out and having to log back in when I just want to turn a light on/off in the middle of the night (because baby) is a PITA.
I'm probably going to ditch Hue in favour of smart switches and dumb bulbs in my next house, so not too worried about it.
