Spotify has taken something that could be used generically too, and just decided to brick it.
Insert something about product and consumers and how its all just some big money game or something somewhere :D
It would have been a better testament to their commitment to prevent these controllers from becoming e-waste if Google just hosted an open source version of the flashing tool on their github from the start.
I know Google graveyards a lot of things, but in the Stadia case, they truly went above and beyond to make customers whole again. They refunded every software & hardware purchase automatically, in full, no matter when you bought it, and also provided save game exports. That means people got to play those games on Stadia for those few years, then got all their money back AND some free hardware (Bluetooth controllers). It was a failed Google experiment, but all us guinea pigs got some free entertainment and swag out of it. Kudos.
