Do you have ideas that can help Mozilla make money? Preferably without abandoning Firefox on the way?
Plenty have been voiced over the last decade. The problem is that none of the observations are ever received in earnest. Particularly starting in the Kovacs years and onwards, MoCo folks have adopted a default stance that if you're not within the figurative walls of @mozilla.com, then there's something you just don't understand as well as the anointed ones do. Meanwhile, none of the moves that the better-knowers have made have ever panned out. And in any discussion that does occur, there are all sorts of rhetorical tricks and intellectually dishonest maneuvers that are brought out to shut the conversation down. The Corporation's insistence on its own competence at this point is a lot like the "I have people skills!" scene from Office Space, only it's not a comedy and just depressing.
There's the separate matter, which is that Mozilla's problem isn't even a lack of money. Mozilla has money (and will continue to have money for at least some time). Mozilla's problem is its profligate spending and that it has chosen for itself a set of decisionmakers with Netscape-levels of ineptitude who can't be avoided.
If course correction is even possible at this point—and it's probably not—then the question is, who are the Hewitts and Blake Rosses and Ben Goodgers in 2020? Has Mozilla leadership even fostered an environment where those types can thrive? (Spoiler alert: the answer is no.)
Admittedly:
1. Wikipedia has more "users" than Firefox.
2. Despite this, the donations Wikimedia receives are only about a fifth of Mozilla's budget.
However, people use their browser far more than they use any single website and hence might be more willing to donate more to Mozilla. (For example, I love Wikipedia, but I've gotten even more value from Firefox.)
Overall, this would be unlikely to cover all of Mozilla's expenses, but I'd also be surprised if donations (after such a campaign) would be less than 10% of current revenue; in any case it'd be a valuable source of diversification.
It's possible that the legal relation between the Foundation and the Corporation doesn't make this possible.
They wouldn't start charging for Chrome, as that's not their business model, but they might move part of their development out of (open source) Chromium and into (closed source) Chrome or further curtail extensions (e.g. adblockers) etc.
The first two are browsers; software, the second two are stores of knowledge.
Browsers have been free for the longest time now, they are a commodity; the 'for pay' browser market died a long time ago. Possibly that was a mistake but that's where we are now and the parties that supply browers (Mozilla, Apple, Microsoft, Google to name the bulk) all try to win marketshare because they benefit from having more users. Putting up a barrier will automatically play into the hands of the opponents.
Wikipedia is a free and much larger alternative to EB, which historically was very expensive. If Wikipedia goes away there is no longer any incentive for EB to have a free tier, which is the one thing they can do to erode support for Wikipedia a little bit.
Apple would continue offering a relatively privacy-friendly alternative — but would require you to switch OS to use it; Microsoft might fork Chromium, but I fear that they'd only pay lip-service to privacy.
Obviously these analyses are complicated by the fact that in both cases the forces that helped create Wikipedia/Firefox wouldn't disappear. If Wikimedia died, then people would put up their Wikipedia dumps online in their own MediaWiki instances. If Mozilla died, then people would either try to keep Firefox alive or try to maintain a set of privacy patches on Chromium. How successful they'd be is another matter...
As more browsers move to a Chromium base, Google might have a similar push to move more of Google's value-add out of the open-source Chromium core to the closed-source Chrome product.
IIRC it started as a fork of Wikipedia from a few years ago, so no idea of its currently quality, but it exists.
Stack overflow has the same sort of setup, for the same reason. (though, that site is far more likely to die/get perverted)
