And while I work for mozilla, I don't always support a lot of the executive decisions. That's been true for everywhere I've worked.
If you want to influence decisions:
1) Use Firefox with Telemetry On.
(That's how we get feedback about things.)
2) Use things like https://connect.mozilla.org/t5/ideas/idb-p/ideas to let folk know what you want or don't want. (Like the return of the RSS button)
3) Contribute. As in: Write code. Submit PRs. Be active.
