Many people think that every important and major information must be sold while other thinks that everyone should know about it for improving knowledge, business and scientific research. In my view, really major information for example about public’s healthy or danger should be free buy comerssial data should be sold.
On the one hand, people who learn something and spend a lot of time to open new method will sell it. Discover something is really difficult and that person has the right not to share knowledge for free. Also if every information be available, researchers will lose motivation to work hardly. It is their work and free major data will access to everyone may be lead financial problem, because really usefull and necessary dates are expensive.
On the other hand, not everyone has money for purchase courses for education and if people had learnt everything free from the internet , they would have been genios. With the free features even the poor people can improve their knowledge. If medical,educational or business informations be access, our country will develope. Also, we could find a reasons for global problem.
Overall, In my opinion sharing information for free may not be wise for those who devote a lot of effort to studying it, and I think that really necessary information should be appreciated.
