There are opposing views on the degree of generosity with information. Sharing as much information as possible can help people develop as a society with easy access to the latest knowledge. However, the existence of some information, specific in nature, might possibly be the culprit for using it for ill-intended purposes, risking national safety.
On the one hand, being open with information to a large degree has a huge positive influence on the development of a society. People with easy access to newly gained knowledge can stay up to date and be more engaged in current global issues such as global warming and political conflicts, bringing in more diverse solutions. Furthermore, it paves the way for independent skill acquisition with little or no charge. For instance, the emergence of platforms such as YouTube and the proliferation of video tutorials have vastly increased the chance to learn a wide range of skills from cooking to coding.
On the other hand, due to the fact that certain types of information require specific expertise and qualification and have devastating effects if applied, it is strongly advised not to share them publicly. In case of doing so, the general safety of the public might be at stake in the consequence of a wrong or ill-intended usage of information. For instance, the guidance on the assembly of explosive substances and the preparation of certain drugs and medicines are hardly to be found online. In addition, to gain access to those kinds of sensitive information, numerous stages of training and qualifications have to be done.
To sum up, evaluating both arguments stated above, it sounds more reasonable to say that being selective about which information to share is the right way to go, considering the safety of the general public.
