The problem is that LibreJS requires adapting all sites using free client-side JavaScript code, or whitelisting all such scripts in LibreJS (they have a whitelist for several popular JS libraries). Has changing all of the Web worked for any other project?
Big free software projects have open issue reports for LibreJS compatibility for years, while it's obvious that their code is free.
