1. All this "1st / 2nd / 3rd world" is from cold war time and not really relevant anymore.
2. Turkey is NATO member since 1952 so it's would be your first world country.
PS: Of course Turkey is not a rich country, but everyone there can certainly afford $3-5 a month for VPN.
UPD: s/user/use/
seems like there's actually two "three worlds" labelings, one by mao, and one by a french demographer.
>As political science, the Three Worlds Theory is a Maoist interpretation and geopolitical reformulation of international relations, which is different from the Three-World Model, created by the demographer Alfred Sauvy, wherein the First World comprises the US, Great Britain, and their allies; the Second World comprises the Soviet Union, the People's Republic of China, and their allies; and the Third World comprises the economically underdeveloped countries and the countries, including the 120 countries of the Non-Aligned Movement (NAM).[3]
this is all assuming that with nation state resources they can identify use of VPNs at the user level.
