I want to spell this out in case the implications aren't clear:
This means all public tools/webapps of GISAID data (all the ones you've been used to seeing thru the pandemic, as far as we can tell) are prohibited.

Insisting on expertise over ideology is not “politicizing” science. The ideologues installing scientific and governmental policy that is contradicted by evidence and data are.
By emphasizing ideology over expertise, THEY have made arguing for expertise and evidence-based decision making partisan.
