I'll admit to being utterly confused by literally the first part, even before the emphasis. What follows is nitpicky, but I'd imagine every word is there for a reason. What does "operate" really mean in this context?

Mozilla(the corporate entity) is operating(=controlling?) Firefox(the software) on my machine?

Mozilla(the corporate entity) is operating Firefox(whatever corporate subdivision on their side) to further my interests as a user (gather telemetry, error reports, "privacy preserving" data about me)? In that case, does "acting on your behalf" mean that the corporate entity is browsing on my behalf? Can I download all the Metallica mp3s using Firefox and forward all happiness letters to Mozilla since they were acting on my behalf? (I know, I know, "You Are Responsible..." section disagrees with my take)

And that's before approaching the can of worms of granting a license which I may or may not be able to do depending on the original license.
