You are missing one very important detail: the people behind any and all ICO's (or any venture really) need money to eat, to pay mortgages, alimony, child support, and maybe even bribes, overdue tax payments, salaries and healthcare copays for their employees. Maybe they just want some money to blow in Vegas.

They raised some money - they now want to extract that money. Obviously, they can't for some reason, either being blocked by investors or other members of their company who are disputing it (or want the money for themselves too).

It's super transparent, and in the end, people are people. An ICO or blockchain, or any technology isn't going to change that fact.
