There's a reason the Snopes piece is mostly based off a Twitter thread. If you actually read the NBC News and Washington Post articles the Snopes piece cites later, they describe the action as part of moving people to related departments as part of the new National Security Advisor's desire to restructure the hierarchy, and the head of the dedicated team resigning after not getting his desire to keep the team the way it was. Not "fired the chain of command".
COVID19 was not a surprise; that is, it was known to exist in China some time before the first cases appeared in the US. It is not unreasonable for a government to assemble a team to respond to something like a pandemic as needed, as opposed to having people dedicated solely to the purpose and nothing else.
You may or may not agree with this. But please don't claim that this is somehow prima facie proof of the Trump administration's malfeasance/evilness.
Considering CDC recommendations have been overruled at the executive level (HHS/cruise ship repatriation, which may have caused the CA cluster due to insufficient planning and training) and recommendations about seniors flying, it's reasonable to assume that chain of command is broken, not that the CDC itself is.
