Just saw Servo is getting full time developers again in 2023! https://servo.org/blog/2023/01/16/servo-2023/
Servo is the "write a browser in Rust" project Mozilla started in 2012 (and which created the whole Rust language as part of the work) - they stopped working on it a few years ago
The new development looks like it's backed by Igalia - "a private, worker-owned, employee-run cooperative model consultancy focused on open source software" based in Spain: https://en.m.wikipedia.org/wiki/Igalia
