It is not the most secure messaging app at all; rather, it falsely advertises itself as decentralized when, in reality, all its servers are controlled by the same developer, making it centralized. Additionally, it lacks a reproducible build, rendering its open-source nature meaningless.

He is a Khaariji and not knowledgeable at all, especially considering his many contradictions. Therefore, taking knowledge from innovators goes against the foundations of Ahlus-Sunnah. We are not deprived of Ahlus-Sunnah scholars.

Ahlul-Kalaam (such as the Ashaa'irah and Maaturidiyyah) do not belong to Ahlus-Sunnah, as they do not share the same foundations. Even the Ashaa'irah and Maaturidiyyah have declared takfeer upon each other.

You are unfortunately spreading falsehood, as the Ashaa'irah consider the 'awaam to be kuffaar. Moreover, they deny that people have fitrah, whereas the 'awaam naturally conform to the foundations of Ahlus-Sunnah.

Ahlul-Kalaam are not part of Ahlus-Sunnah, as they do not share the same foundations.

Taking Daniel Haqiqatjou as a reference without understanding his underlying ideological perspective is another issue that promotes perceived solutions lacking any scholarly basis from Ahlus-Sunnah.

Your optimism is misplaced and you have unfortunately misunderstood what it means to be a scholar. Moreover, it is not about following personalities but rather about learning the foundations of Ahlus-Sunnah and its true scholars. Thus, shifting from Irjaa’ to extremism in takfeer is not a solution.
