This is not surprising, and unfortunately, this situation is unlikely to get better any time soon given our increasingly conservative (corp friendly) federal courts. It's really a shame because these corps have shown they can't be trusted to properly archive their own games, and any change of ownership or economic fortune can mean they are lost forever.
From a personal level, I'll just keep doing what I've always done. Help archive the things I can. Support and buy games from smaller devs or publishers who care about their games. And if you want to play something from a shitty AAA dev, nothing is stopping you from playing it anyway for free and just giving the money to your favorite charity instead. Consumers can have a lot of power if they choose to exercise it.
