All of these are fun to use for both the old and young as well as the urban and rural. The old can keep in touch with their children and grandchildren while the rural can connect to more modern and urban relatives. Everyone benefits and everyone is happy having access to the technological developments.
On the overall, I don’t see any reason why people of a nation, especially a developing one should lack the privilege of using technological developments because they too form the media of education and learning and hence literacy. If a nation gets encouraged to develop themselves through these means, why not? Give them access and rights and they will not only love it but also benefit as well.
