I don't think you understand how patreon works... (I don't use patreon but I do know what it's about. I was considering getting one awhile back because I'm a poor artist)
I don't understand why you guys are complaining. there's a working version up and running for at least 1.7.10?
also an open beta sounds cool. I can't wait~
You don't understand how the Minecraft EULA works. He's charging for access to the beta via Patreon. This is 100% illegal, plain and simple.
As to the currently available one for 1.7.10: it's rather broken at the moment as it requires several Minetweaker recipe fixes to get some of the crops working.
