The commitment is to develop privacy-preserving advertising. If successful, it would revolutionize privacy because, as we know, ads and their surveillance are everywhere.
Instead, maybe nobody will work in that project if you succeed in slandering Mozilla.
You can't have "privacy-preserving advertising". Either you track users to ensure ads get displayed (because the places you'd serve the ads wouldn't serve them if they could/claim more ad views than happened), or you have no clients (because their ads aren't displayed). Broadcast works for ads because the clients can verify that you are broadcasting (and it means you can disconnect the group serving the ads from those who verify "views").
