It also discusses sociopolitical issues like threats to privacy and freedom of speech from nationwide filtering and shutdowns.

Its becoming a huge pressure to the ISPs to comply with the Government order to block specific content. 3. IP Address, App ID, URL, etc. based Blocking blocking the right to use internet / content wholistically in respect to that resource, which is not fair. 4. Man-In-The-Middle attacks actually breaches the data security, incurs the identity theft and it is opening up personal data and user right to attacker. This method is eventually illegal. 5. Blocking a specific content to a specific user base, can easily turned out to be, Blocking the entire service to a whole nation.
