There are many times when I am playing a game and will often think there was a better way to do some aspect of it. The alpha edition of Galactic Civilizations III was designed to allow this feedback to go back to the developer. The only problem is that if you open that process up to everyone or even to the wrong people, then the final product is not what it could be. So offering a $99 Founder elite option is a great option because the price point serves as the gatekeeper to filter people.
Sadly though this a filter with no settings, anyone who can throw up that money has the chance to influence the game outcome. I am guessing but willing to stake that in the past beta testers were hand picked based on what they could offer in constructive criticism. Now all a developer is going to get is input from the internet, and has been demonstrated many times in the past there is no more stupid entity than the internet.
I agree that a developer should be careful who they open up testing and influence to as it could radically alter the direction of the product. But no amount of price limit is going to work to solve that problem, price to low and you get the entire world mailing you their latest amazing uber idea. Price too high and you get nothing but extremely wealthy folks who now demand flesh for their coin.
I personally know of only two good early access games and they are both free, the thing that makes them work is the very fact they are free because the players do not have any expectations or demands. The second you ask for money you make someone a customer and they are entitled to make demands. If you then start saying things such as "this feature doesn't work yet" and so on, you only serve to piss off your no longer prospective but now very actual customers, and in turn you are totally changing the seller/buyer dynamic. With very few exceptions the whole early access style developing that is taking place lately is folks seeking shortcuts into an industry that others will have done the grind for in the past. This just allows people with little to no experience in actually running a project to completion quick funds with no responsibility for them.
