1. Some countries have declared if crypto didn't meet all of the regulations that already applied in those countries. These countries were also prohibiting its investors to participate in any investment that can't fullfill the requirements to be called as an investment based on its regulation. Rather than putting the investors in the risk and icos have been deciding to ban those countries.
2. The marketing participants will be paid by the shares of the company ( i can't call that as nonsecurity coin considers about it has no utility usage). this is having the same definition just like an investor who is exchanging its effort to get paid by the shares from the company. This thing was also prohibited by some countries.
I believe that those requirements will simply be requirements that will ensure that their investors are well protected and I think that the major requirement would still, l be the data protection that the exchanges are clinging on, they initially do not want to accept the enforcement of KYC on their citizens, but we can see how they have finally come down to the level of government.
I am sure that one of these country is US, they must have really been hard on some of these exchanges as regards their KYC, and I think it is this reason that is making binance now to separate account of US citizens in other to follow the rule of US concerning their citizens participating on anything regarding investment on the exchange and I think this will only succeed in turning this whole system to a centralized one.
