This really isn't groundbreaking news, and the FBI's assessment is far from a conclusive determination. What does appear to be most likely is that however it made its way into the human population, it was not genetically engineered or released intentionally.
From the DNI website:
"The IC assesses that SARS-CoV-2, the virus that causes COVID-19, probably emerged and infected humans through an initial small-scale exposure that occurred no later than November 2019 with the first known cluster of COVID-19 cases arising in Wuhan, China in December 2019. In addition, the IC was able to reach broad agreement on several other key issues. We judge the virus was not developed as a biological weapon. Most agencies also assess with low confidence that SARS-CoV-2 probably was not genetically engineered; however, two agencies believe there was not sufficient evidence to make an assessment either way. Finally, the IC assesses China’s officials did not have foreknowledge of the virus before the initial outbreak of COVID-19 emerged."
The report goes on to note that the intelligence community remains divided on the most likely origin of COVID-19 (with which I'm currently suffering, BTW).
