these countries are just denying their country from the modern development of internet and online business, If they will not allow their nation for bitcoin then they will not be able to do any online deal as in the near future everyone is going to adopt bitcoin for their use.
but as still in most of the countries the government have not yet given any statement about bitcoin therefore all the people of these countries are using bitcoin in the same way as there is no banned on bitcoin there, and still there no tax on bitcoin.
