I don't see it any other way, some speculations can be generated but there is no need to echo this much, just someone who wanted to share this and that's it.
I don't see anything wrong either.
Not every time such an event is announced does it always have to be an in-house representative. It can be a player who likes the event and wants to share it so that more people know about it.
To me anyway that kind of freerolls do not attract me much, it's a bit like playing the lottery for free but you have to be actively playing for a long time to try to win.
