Discussion: Oauth token required for all mobile access

It looks like oauth token authorization is required for all mobile access - even for API's that supposedly do not require authentication. 
Clarification: For mobile app access to the API, it appears authentication is required, even for methods that the documentation indicates, "This method does not require authentication."

such as http://developer.glitch.com/api/explore/#!players.fullInfo and others 
yossi, where are you seeing this info?
