The maintainer of uBlock Origin – arguably the most well-respected content blocking browser extension – has removed a set of filtering rules because they took a political stance. It's a development that underscores the vulnerability of trust-based community projects.

A GitHub user raised the issue on Wednesday in a bug report, noting that a Finnish addition to the widely used filter rule set EasyList, called Adblocker for Finland, had taken a political stand in an ongoing dispute between workers and the Finnish government by blocking several union websites.
