But Sonny is not protesting or something, so we cannot say anything about it.
The problem is that many feel that she is not a good leader for Mozilla today, not that she is not a historical figure for Mozilla and the open source community in general.
Sure - let them squeeze out the last drop of their one and only cash cow before it becomes utterly irrelevant - instead of investing in it and making it a core pillar of their strategy.
>See how Wikimedia Foundation is basically flush with cash,
Mozilla was (is?) flush with cash. Browser market share and corresponding user eyeballs are immensely valuable. That money isn't going back into Firefox development. This is why it is borderline criminal that they choose to focus on everything except Firefox.
Alternatively, what are they without Firefox?
Now Firefox can't be used to make webapps effectively, the only alternative is to use Electron and fortify Chromium's monopoly.
If Mozilla tried to address this, I think many Chromium-based browsers today would at least try the possibility to be Gecko-based.
