Which horrible behaviour from backers have you seen? Please can you explain to me what you meant?
Let me give you an example:
Dev: "Hello everybody, my vision for this project is to be a fun car game."
BackerA: "I backed you at god tier. I demand you add boats."
Dev: "Update: The project will now be a fun car-game with boats too."
BackerB: "This game needs dinosaurs. Who's with me?" Creates poll on project's forum. Thread hits 1000 pages.
Dev: "Update: The game will now be a fun car game with boats and dinosaurs.."
BackerC: "All the big AAA games have zombies. We have to have zombies too or your game cannot compete!" Another huge thread on project forum that spans many weeks.
Dev: "Update:The game will now be a fun car-game with boats and dinosaurs and zombies."
At no point did any of the "loudest" backers respect the original vision of the dev for this project.
(You know... the thing we all initially backed)
