I sincerely hope it's neither. I'm well aware that a third party can't direct Mozilla as to how to channel its resources. They can however ensure there are sufficient contributors external to Mozilla to maintain the features they wish to keep.
Even if the end decision is still made by Mozilla internals, the decision to keep functionality is much easier if they don't have to battle for resources to maintain it thanks to external contributors being willing to do so.
At the end of the day, being an open project does not require the maintainers to do work simply because a subset of users wishes it.
Can you please edit out gratuitous swipes like that from your HN posts? It breaks a number of the site guidelines and your comment would be fine (with higher signal/noise) without it.
What's gratuitous? Is "naive" considered an insult on Hacker News?
It may have been a bit of a stock comment, but I see no evidence that it wasn't in good faith.
On the other hand, it only takes me a few seconds to complain on the official channels when they add a feature I don't need or remove one that I use so I think I'll keep doing that. Maybe enough users will agree and Mozilla might react to the complaints. Probably not though, they've been pretty deaf to the community lately. A change of CEO might be a chance for that to improve, so that's why I made my comment.
