I'm pretty sure you are right now paying a lot more money to companies doing a lot less efforts Mozilla is currently doing. And now you are asking even more of them, just as a condition for maybe giving them something day.

This is a zugzwang and the sooner they break it the better. With a bit of wishful thinking i would have hoped they would flip the table and go full on with hardcore gnuish philosophy, making a big move and a new political depth into their browser. Perhaps regaining some sympathy from people that have long considered them as compromised, perhaps destabilizing big web players which will again have to face some public rumble to which they can't easily say anything else than "yeah we screwed up but hey it's not so bad and we are getting nicer" (an answer which is starting to get quite laughable).
