One of the things which turned me off to Steam was how they overwrote secure directory perms, to make it so that all users could modify folder, which only Administrators should be able to modify. Sorry Steam, you're insecure.
This. I want to cheer Steam as much as the next person but the Steam app is a fucking security disaster. I love Gabe but the dude is a crappy CEO. The flat management style at Steam means nothing gets done or things get half done because no one has the authority to power things through to completion.
Gabe saw the writing on the wall with Windows 10 and started SteamOS as a response but where is the follow through? It's stagnating and dying on the vine.
