That's unfortunate that updates will break games on Steam Deck that had previously been working fine through Proton. But unless we want Valve getting in the middle and requiring various validations like Microsoft and Sony do on their consoles, there's not much that can be done about it. A strong refund policy on Steam might help, but to have any impact it will require significant numbers of Steam Deck users to initiate refund requests when compatibility breaks.
I still have hope for Linux gaming because the Steam Deck clearly has appeal that goes beyond the extreme niche that was Linux gamers prior to the Steam Deck's release.
