Then you'll need to educate me on the what you think distinction is. The linked tweet thread asserts both: that the virus was manufactured in the WIV and that it leaked by accident. There are stronger (and even less well grounded) ideas in the broader conspiracist community asserting that it was the result of bioweapons research, and sometimes even that it was deliberately released. Ebright himself doesn't truck with any of that nonsense.

Distinction:

- lab leak: researchers catch infected bat; at the laboratory, bat bites researcher; researcher gets COVID

- lab made: researchers modify a virus, and produce SARS-CoV-2; the latter escapes the laborary (in one way or another)

The importance of the lab leak hypothesis is that it doesn't need any conspiracy (a researcher being bitten is nothing strange in itself), but still implies unsafe practices and bad faith by the institutions involved.
