I also hate it when project developers act arbitrarily after they have successfully completed their fundraising target. There are even who stop deploying or suspend their projects for various reasons and run away with investors' money. They are really greedy and irresponsible.
It is true that project development is controlled by the project itself, but every investors are entitled to enjoy the investment returns that they have promised, without any reason.
It is rare that project developers respect bounty campaign participants. All this is because we do not conclude employment contracts with them and they always write that they can change the conditions of the bounty campaign. It is very good that there are not so many deceivers among the developers. Once I was deceived with the timing of payments of coins. They were transferred to me after the price of the coin dropped dramatically and I earned 10 times less.
