To anyone who can understand Urdu or Hindi, it's trivially easy to find speeches of terrorist leaders on YouTube. Hundreds of thousands of people have watched instigating speeches of Masood Azhar, Ilyas Ghuman, Israr Ahmad, hundreds of thousands of "likes" on the videos, thousands of appreciative comments.

This is the truth. It's also why Twitter, Google et al censored radical Islamic content and worked with the government to identify extremists.
