blocking FLoC

[vv01f]

@daveajones
not directly on the content here, but suggesting to do this for the websites of the project

details on the topic:

• https://www.eff.org/de/deeplinks/2021/03/googles-floc-terrible-idea
• https://spreadprivacy.com/block-floc-with-duckduckgo/

how to block with nginx: add_header Permissions-Policy "interest-cohort=()";

how to test a webservice: curl -sI https://ds.ccc.de | grep -i "Permissions-Policy" && printf "Above policy found.\n" || printf "No policy found.\n"
expected part in header: "Permissions-Policy: interest-cohort=()"

btw. Permissions-Policy … that used to be called Feature-Policy
