Why was hadith banned?

Why was the practice of hadith, or the collection and transmission of sayings and actions attributed to the Prophet Muhammad, banned in certain contexts? Was it due to concerns over the authenticity or accuracy of the reports? Or was it a response to perceived threats to religious orthodoxy or political stability? How did the banning of hadith impact the development and evolution of Islamic thought and practice? Can you elaborate on the historical and cultural factors that may have contributed to this decision?
