Because I have realized that the world tends more and more to do open and free science and there is a trend more and more to choose free databases, free tools and open access platforms.
The world doesn't restrict anyone from being science-oriented. Developed nations chooses science because of it imminent importance. The goal of open and free science is to increase the accessibility and impact of scientific knowledge and to facilitate faster and more efficient progress in our society. I think open and free science is a step in the right direction toward granting access to people to explore it and equally benefits from it.
