Like I said, if you own the game in your library you will always be able to download it. And I don't think there have been any instances where Steam has allowed a developer to purposely corrupt their game.
So if you've bought Firefall[1] or Dead Island[2] I am sure you can still play them. The store listings might've been removed but they'll never leave your library and they'll never leave the servers.
Even if the developers did intentionally worsen a game with an update, you could still search steamdb for the older version and attempt to manually download it.[3]
As for Steam pulling their own games, they're notorious for not doing so. For most of Valve's games you can download older versions as a beta. With CS2 you can play the original CS:GO on the csgo_legacy[4] branch. Just right-click the game and go to "Betas".

I literally own two where this has happened.

Dead Island maybe, Firefall definitely not as it's an online only game. However I'm not sure your point, I already stated that you can download them anyway.

This is not the same as keeping the game you originally purchased. And it was also not really my point.
Steam has removed games from their platform. I'm not sure why you're arguing this easily searchable fact.
