While what you’re saying is factually correct, my biggest pet peeve is that Firefox is entirely owned and developed by the corporation. If I donate money to Mozilla, it ends up with the silly projects instead of the browser.

To me, this is a problem, and while it’s documented somewhere, it’s not nearly communicated well enough on their website when you’re actually making a donation. As a matter of fact, it’s sometimes even downright misleading.

As such, I don’t believe the corporate structure is a healthy one, and the organization(s) are not properly aligned in where the profit comes from, where they make the biggest impact in the world, and where the donations go to.

When you say "Mitchell Baker owns it all", you aren't claiming that Mitchell owns Mozilla Corp, are you? Mozilla Corp is owned by Mozilla Foundation, as described in the Wikipedia article: https://en.wikipedia.org/wiki/Mozilla_Corporation

Most Mozilla employees draw their salary from Mozilla Corp.

Who owns the foundation?

No one. It's a 501(c)(3) non-profit organization.

But she’s the chairwoman and has full control. I think we’re arguing semantics here.

She controls everything. Including her own comp.

That's not how non-profits work. There's a board of directors:

If the board were to decide that Mitchell's time as leader was done, they could do so.

Mozilla corporation is fully owned by the foundation though.
