Maybe not the wrong message, but maybe a little brash
Elite can be hard, thats the game. i think the point the OP was making is stop whining about it, and get on with it.
But again, you have to bear in mind that the stuff people are whining about (and I keep stressing it's a massive minority) are the same issues that (some) Alpha backers were complaining about when they were going through their releases. It's much easier to say "stop moaning and get on with it" when you've been getting on with it for several weeks/months, as opposed to a couple of days. Alpha backers got frustrated at various issues, are beta testers not allowed to be frustrated? (and remember if you think that only 1-2% of backers complain, there'll be a higher amount of beta backers "whining" based on the fact that there are a lot more of them)
