On a second thought, Otherworld will like every player around the world to patronise them. But in reality, it is just different. This means that the issue of restrictions bothers Otherworld than us because they are into business. So, let's be patient with them as they go about this process.
Each jurisdiction has its own regulation when it comes to gambling. Even though Otherworld wanted the whole population to be their players, they must comply with the policy of each country, or else they will be bombarded with lots of issues and problems from countries that restrict their citizens from gambling. Every business owner does not want to experience that so I do not think they will bent their rules on the restricted country if it has something to do with the government policy.
Each jurisdiction really has their own regulations, also there are some jurisdictions whose regulations are not very strict. Otherworld could concentrate on those jurisdictions with minimal regulations and explore.
I actually tested different locations with VPN and I felt that there are some locations that are not supposed to be restricted due to weak regulations in the country but they are still restricted. No one can actually please the government. No matter how law abiding and compliance you are, one day the government will betray you.
