You have got to be kidding me. EOS is not even close to being a security. It promises nothing in return and is an open source software that will be released. You sure wasted a lot of words and don't even understand what EOS is.
The securities law is based on the profit expectations of investors, not what EOS writes in their legal documents which do not reflect the economic reality of the situation.
Do you see Blockone actively ensuring that the EOS tokens will not have any value? Did they sue the exchanges to prevent the tokens from being listed?Open source does not help them avert the securities regulations, because for one thing they pooled the funds raised and are expected by investors to use those funds to develop the open source.
The investors expectations are proven by the comments in this thread. All the SEC has to do is capture this thread. Note I have archived this thread at archive.is to help the regulators.
As far as US buyers using VPN to get around getting EOS tokens, 99% of other ICO's have allowed the same loophole. They gave the same warnings with even stronger language discouraging US buyers
Nevertheless, the US buyers side-stepped the controls and thus EOS (i.e. blockone) has likely violated the law.
Disclaimer: IANAL. This is not legal advice.
