“Apple already prevents users from installing software outside of its own software store, meaning third-party software stores, like Steam, are not allowed.”

Yes, for iOS based apps, you are restricted to the Apple app store (unless you jailbreak), but for OSX – which is the platform you would run steam on – that restriction doesn’t exist in the way that the author implied that it does.

By default Mountain Lion does restrict you to MAS based apps, but in the security settings in the System Preferences, you can change that to allow to install apps from any sources – so, the line the article author wrote claiming you couldn’t install steam on the current version of OSX is wrong and the facts should have been checked before the author wrote that. Here’s a reference if you don’t believe me:

Here are some sources, and I am sure I can dig up more that validate the what was said in the article.

umm not true, and never has been. i suggest checking your facts before you publish articles…
