Moving away from Mozilla, regardless of destination, presents an opportunity for the most powerful stakeholders within the community to exert greater influence, many of whom I would be less comfortable with than Mozilla.
Rust, though, is already at Mozilla, whose influence seems to be benign.
I'm curious, which Mozilla entity holds the trademark: is it the 501(c)(3) Mozilla Foundation, or is it their for-profit subsidiary, the Mozilla Corporation?
I never thought about this, but TESS says it's Moco, which is what I'd expect.
For what it's worth I would have greater confidence in such an arrangement than I would in a 501(c)(6) Business League version of a Rust Foundation, which would in my view undermine independence.
