I'm not sure the new branding accomplishes the goal, but it is a worthy one. If it helps persuade more people to support/use Mozilla's projects, it's a win.

Folks that care about the org wasting money, not keeping the retro dinosaur, folks that think branding is a waste - they probably already support Mozilla. No one's gonna switch to Chrome over this. Maybe if it's shown Mozilla is really actually wasting money like and mismanaging things, it might hurt their open source participation. Or if they publicly got super political.
