Your [0] link mainly refutes one specific theory, of Li-Meng Yan, about intentional military engineering. It does not refute the wider range of possibilities where a lab escape was part of the path from nature to human circulation. (When that article points out things like "Scientists have yet to find the direct parent of SARS-CoV-2 in feral beasts", or that with regard to some specific Chinese-military-catalogued viruses Yan fingered, "bat coronaviruses were circulating in wild bats and could have been discovered by anyone", it's saying things very consistent with the chance that this could be a wholly natural virus that was carried to Wuhan & then escaped into that urban environment via lab collection then escape. There were a lot of researchers carrying novel natural strains from caves back to labs!) Your links [1] & [2] are interesting but seem to include no opinion or reasoning for or against a lab escape or lab-enhancement, either way.
