Nobody trusts a Moscow-based company with a lawyer and PR office in the US. To see this, simply set up a single webpage with a Paypal button advertising for this product. You will get money, but probably not 1M$.
On the other hand, people seem to trust IGG and Kickstarter (at least to some extent). This can be demonstrated easily by observing that content which would – on a normal website – not collect any funding seems to do well on these platforms.
So, no, it is not entirely about criminal responsibility, but about a misuse of trust, trust that IGG has and which it conferred to some company by letting them use their platform.
