It is contentious to whether to open information related to like scientific research (비즈니스와 교육 쪽도 언급해주세요.) to the public should be opened or not as a source or not. People who disagree to share sharing information for free believe that there is potential importance in some kind of information. However, it may be argued that a better world will be made if the information becomes a free source.
To begin with, sharing information can lead people from all around the world to become even smarter as they can learn freely from databases that some have been shared. Limited access to business and academic world is resulting more people to become stuck in their academics because they do not have moderate answers to follow.

On the other hand, scientific researches and other kinds of information cannot be opened freely. Firstly, as the information was gathered precisely and carefully by experts, it cannot be spread among the internet without any costs. Also, as it is thorough and reliable to use as a sample answer or model for their study, it needs to be paid in order to pay for efforts of the information owner and to keep 'copyright'.
In my honest opinion, I believe that information should be paid by people who want to use it. Not only because it is trust-worthy content but also it is expert's own copyrighted information. (이 부분의 경우 결론에서 같이 언급해주시면 됩니다. 굳이 독립된 문단으로 넣을 필요가 없어요. 대신, 이 밑의 문단에서 너무 요약 식으로 되어있는데, 이 대신 내 의견만 쭉 밀고 나가면 되고요.)
In conclusion, to educate people without any cost is one of the reasons why some people believe information including researches in various subjects should be opened for public. However, keeping owner's copyright as it is detailed content outweighs educating people freely. Thus, it is better not to make information as a free source.
