From xcancel:

The team behind uAssets, the filter lists used by uBlock Origin, says it will stop fixing ad-blocking issues on Facebook. They say Facebook keeps finding ways around new fixes, making the work increasingly difficult to sustain.

This won’t affect AdGuard’s Facebook filters. We maintain our own rules and will continue updating them.

There’s nothing to celebrate here. It shows how hard it is for small, often volunteer-run teams to keep up with tech giants — and how important their work is for everyone who wants more control over what they see online

uBlock Origin offers some AdGuard rule sets, so I don’t know exactly what this means for existing uBO users.
