1. Potential donors get upset that they can't make directed donations to specifically support Firefox or Thunderbird rather than the whole kit-and-kaboodle

2. Separate entity spun up to focus on Thunderbird only. Now you can support Thunderbird development directly.

3. New separate entity is now in the business of extensible AI clients?

EDIT: I went back and read the launch announcement [1]. I'll concede it does say "will also allow us to explore offering our users products and services that were not possible under the Mozilla Foundation" which could mean anything, really. And this development was funded by a Mozilla grant, importantly not by Thunderbird donors. I'm still struggling to not see this as a distraction from the core mission. I wish they'd spun up a new entity instead.
