Provide a rules quote for that claim and I'll concede the matter. (Hint: one of your own rules quotes above contradicts you.)
A specific rules exception is not a contradiction.
But supporting my claim of Free Actions only during your turn, no problem:
You can perform one swift action per turn without affecting your ability to perform other actions. In that regard, a swift action is like a free action. However, you can perform only a single swift action per turn, regardless of what other actions you take. You can take a swift action any time you would normally be allowed to take a free action.
...
Much like a swift action, an immediate action consumes a very small amount of time, but represents a larger expenditure of effort and energy than a free action. However, unlike a swift action, an immediate action can be performed at any time — even if it's not your turn.
Swift actions can be taken ANY TIME you can take a Free Action with the exception that you are allowed only one per turn.
Unlike Immediate Actions, you cannot take a Swift Action when it is not your turn. Hence, you cannot take a Free Action when it is not your turn (unless a specific rules quote indicates otherwise like with a single Readied Free Action). Otherwise, there would be a contradiction of rules here.
Your interpretation requires a contradiction of these rules. Mine does not.
When there is a strong implication in the rules (as in the case of a free action only during your turn), you have to look at the rules at a whole to determine if the implication is valid or not. We have multiple places here where there is direct indication that Free Actions are only normally done with other actions during your normal turn.
PHB page 135:
Every round on your character's turn, you may take a standard action and a move action (in either order), two move actions, or one full-round action. You can also perform one or more free actions along with any other action, as your DM allows.
Just like full-round actions here, free actions are only allowed by this quote on your character's turn.
Rules of the Game:
http://www.wizards.com/default.asp?x=dnd/rg/20041102a
Note that you can take a free action only during your turn.
There are multiple entries of this within Rules of the Game.
Your interpretation requires: 1) a contradiction between the language of free, swift, and immediate actions; 2) the quotes on page 135 and 139 refer to outside your turn; 3) an assumption that the "turn" language of free actions and of readied actions means "action", not "turn"; 4) the specific language of the speaking free action is not explicit language; 5) the singular language of Readied Actions is not explicit; 6) the words "normal" and "normally" have no meaning in the interpretation; 7) feats that explicitly specify that you can normally do something as a free action during your turn have totally redundant information in them (e.g. Combat Defense); 8) the FAQ is in error here; 9) the Rules of the Game are in error here.
You have to read the entire ruleset here:
Action Types
...
In a normal round, you can perform a standard action and a move action, or you can perform a full-round action. You can also perform one or more free actions.
...
Free Action
Free actions consume a very small amount of time and effort. You can perform one or more free actions while taking another action normally.
Like page 135, this only discusses your actions in a normal round. Not AoOs. Not Readied Actions. Not actions outside your normal round or normal turn. The one quote you are relying on for your interpretation is imbedded within the description of what happens in a normal round under Action Types.
