From Jolla's response: "We are today participating in the openly developed and open source Mer and Nemo Mobile projects which includes sponsoring parts of their operational budgets. These projects have very small budgets and have based their operations around being able to do big things"

Are they aware we're only asking for a small donation? $1000 would go a long way.

In addition to an open letter, I strongly recommend private negotiations regarding what TMO can do in promoting Jolla and particularly development for Jolla as well as future collaboration when the first Sailfish device is finally released.
