If they want to give some kind of meaningless cosmetic bonus to people who participated in EA, I'm fine with that. Maybe we get to wear blue hats and no one else does. I don't personally care about it, but it's no big deal to me.
I'd be very much against them giving something meaningful to people who participated in EA and not to people who, for any reason, didn't participate. Meaningful exclusive content is obnoxious, especially to the people who didn't happen to be around to receive it, but I don't like being on either side of it.
