Firefox's owners can be corrupted and focused on the wrong things (i'm not saying they are, btw - actually i do not exactly agree with the idea of Firefox having "owners" in the first place, at least not the same way as Microsoft owns Windows) and have the wrong priorities. If you consider that Firefox needs to do things right, you may want to prioritize making Firefox "good" (whatever that means, e.g. making it the fastest and/or most secure browser and/or giving the most control to the user, etc) and then (in terms of priority) try to promote and create a marketing campaign that focuses on those aspects of Firefox. It isn't like marketing is all about style. And even if it focused on the style, one might disagree that the proper way to go about it is to copy Chrome.
There are many ways to interpret these two paragraphs as not being contradicting.
Specifically, the original poster's paragraphs seem to contradict each other: the first suggests 'not fighting the good fight' because you have to appeal to consumerism, and the second blames Mozilla for not fighting the good fight and appealing to consumerism.
I also don't know why the account age has anything to do with this -- they're not pointing out a typo, they're pointing out a logical contradiction.
Some of the Firefox-only things I like are it suggesting Reader more more often, and the Page Info view. They're the kind of small conveniences Chrome is missing.
[EDIT] Oh, and being able to use bookmarks to sync custom searches across devices was AMAZING. Of course, that had to die. [/EDIT]
And of course zero knowledge sync and uBlock on mobile are huge, which Chrome itself has a less excellent record on. But some of the Chromium forks like Brave and Vivaldi not only offer those, but also good tab groups.
The big thing with Firefox is that its enthusiast userbase is moronically hostile to Firefox gaining financial independence of some kind. They bought Pocket and integrated it and people were just about ready to lynch the Firefox/Mozilla team. A lot of them are more motivated by the kind of purity that makes people install gNewSense and complain about companies doing business than any desire to have an actually useful tool with independent revenue streams.
Already in 1947, Georges Bernanos wrote: "it's always more profitable to satisfy man's vices than his needs" in his essay "France against Robots" (La France contre les robots, no idea if there's a good English translation though). Slightly off-topic but I can't recommend this book enough, it's quite forward-thinking and the chapters on freedom and privacy in an increasingly technological society might interest some of you here. I especially remember a brilliant rebuttal of the 'nothing to hide' argument that is still relevant nowadays.
So yes, I agree with you, good ideas by themselves rarely happen to actually change how things work. Like you said "a good marketing campaign" might be more impactful. Is there still hope? I've had this question for quite some time now: how do you efficiently implement some change in a system that won't cooperate? Seems to me that it requires some hacker mindset to find how you can exploit the rules of the game to trick the system into working towards your goals.
I've been given a great book full off details about what should be done if we are to improve our world in the coming decades, but it's a bit of a let down for me: what should be done is rarely a secret, how you actually manage to pull it off at scale is the real issue.
If you want to see a counterpoint to this, watch Goebbels' Total War speech. You can absolutely mobilize a great mass of people by promising them pain and hardship. Similar idea with JFK's moonshot speech.
You're missing one component, which is that the Nazis took all of these (more or less) legitimate grievances and redirected them into the figure of the Jew. You're right in that this wasn't a result of some supernatural ability of Hitler and Goebbels, and that's the whole point. There doesn't need to be. I'm sure individual Nazis had similar thoughts as you do (this is just another motivational speech, these are decent campaign promises, etc). The precondition to repeating Nazi ideology is already present in normal psychology.
Also, Firefox isn't some beacon on a hill. Its creators/owners are intensely corrupted at this point: politically, ethically, and pragmatically. They stopped building a tool to serve ordinary people a long time ago, and pivoted to attempting to build the most stylish and trendy browser instead. IE, a browser that looks as much like Chrome as possible without being Chrome. Firefox is still better than Chrome, but the differences become more superficial with each release, and I wouldn't be surprised if it eventually just becomes a shell for Chromium like everything else has, a way for a certain crowd to signal how ethical they are while still being tapped in to the Gooogle ad hivemind like everyone else.
