This has been noted somewhere else on this forum but I can think of countless video games i have bought, played for about a month then have 6 or seven different patches to correct the game etc. These are downloaded for free. Making changes to the dynamics and rules of a board game is no different. It is a patch for the board game. It could even be classed as an expansion for a board game which you would normally pay for if it was a video game. Let the creators do their thing. Its their project they can do what they want. There will be a final version, just be patient.
