The allocation may be unfair, however I don't really get why some big Chinese investors are ready to sell so low right now : don't they believe in future high prices for BTS ? Even if one feels robbed by the allocation, BTS still have the potential to go to the moon, and even more after the merge.
I am European, I am not Chinese and certainly not American, but I think it is not neither about "changing the rules" but rather a principle. I feel it like that.
A lot of successful people say that it is necessary to stick to your goals with tooth's and nails.
And often the first decision is correct.
