How can you be so entitled? The dev is developing the game for free, what's wrong to give privileges - early access - to his financial supporters, which totally don't hinder others enjoyment?
It's not like you "NEED" to play the latest version to SURVIVE.
Not to mention Voting for contents is a worse way, as that means the dev don't have a clear direction, his will just be selling his labours, like commission arts. The game will either become in-consistent, or being drag out that never finish.
And mind you, lot's of games do both EA and Voting, they are not mutual exclusive.
Also mind you, 1-4 weeks delay is totally endurable (not so much for 3-4 tho). There're some games only put out public version every 6 month or worse.
