Mozilla is going to sell users data...

I sympathize with finlannoche's sentiment, but it's true that money is not the only tool of tyranny, it's merely one of its most (in)famous representations. Even during the early phases of feudalism (where currency didn't exist) oppression was still high, instead of selling themselves through money people simply were forced to pay in other ways such as work, being forced to hand out grain to the feudal lord and forced allegiance to Catholicism, so even if money didn't exist the oppression encouraged by money would still exist through other forms of power, money is not the only representation of tyrannous power but simply one of the most obvious ones, other forms of oppression and power are undemocratic States (which would still seek profit in the form of political capital even if money suddenly stopped existing), proprietary software (which is still oppressive even if fully gratis with money not being involved), non-democratic corporations controlling factories in a way that oppresses its workers (even without currency these corporations could still demand work by hoarding goods through the concept of "private property" and only handing out these goods to people in exchange for work).

Money is simply one of the methods of tyrannical power, but it's still possible to have tyranny even without what's currently known as money, money is only one of the methods of trade where people give up their bodily autonomy in order to survive. The ideal would probably be to get rid of money, but also;

* concentration of capital where a few owners are able to undemocratically own the workplace where the working many work in bad conditions. We should achieve post-scarcity society where there's enough automation for everyone to have enough food and be able to do what one truly enjoys instead of being forced to work in a job one is not happy with, but even in places without automation where humans are required the workplace should be humane and democratic

* undemocratic governance such as
* * presidentialism (where they concentrate large amounts of power on a single "representative" creating a cult of personality and unhealthy dependence trying (and failing to) represent millions of people through one arrogant person and trying to make the country's policy aligned with the wishes of this person, only for this person to become rightly condemned for violating the people and be replaced in a few years by someone who's going to do the same thing abusive crap again just in the "opposite" direction).
* * tyranny of the majority (the people voting to take away the rights of oppressed minorities), speciecism, ableism, antiveganism, social darwinism and other forms of a majority imposing oppression upon an struggling minority. People should see eachother as sentient living beings rather than believing they are in some sort of competition where they need to cause the most suffering possible upon the other person in order to come out on top

The problem is not money itself, the problem is those who use it as a tool to control human beings.

> Notice how people hate on FSDG-distros for "taking away user choice"

I haven't seen this sentiment much. Looking up some Reddit threads on Trisquel, it seems that mostly people just say that they wish they could use it (or another FSDG distro) but their hardware doesn't work.

I'm sorry but it's just unrealistic to expect even most free software supporters to replace their WiFi chipset with a very old one. Even people on this forum make compromises, in that most aren't running an ancient Thinkpad with Libreboot. Can't really blame the users for wanting recent, functioning hardware. We should blame the hardware manufacturers instead.

Edit: You mentioned veganism, and I'm also a vegan (for over a decade), so I'll put it to you this way. According to the definition, veganism seeks to exclude animal exploitation "as far as possible and practicable." So you can still be vegan while taking necessary medication that contains animal products or is animal tested. I would argue that firmware is analogous to this, as most people cannot practicably avoid it. (And this is an issue that, in my opinion, is more important than free software. If for whatever reason I had to either compromise my veganism or use nonfree software, I wouldn't hesitate to choose the latter).

I hope they are at least raising the alarm that non-free firmware replacements are needed in the process.

Mozilla disappearing, I could see.

Firefox code and code development disappearing, I could not see.

By most recent accounts, Mozilla is a very poorly run organization which is unable to properly prioritize its own staffing and production schedule, or even which products to work on or which mergers and acquisitions to enter into. It would not be shocking to see it disappear as an entity if and when the Google money vanishes.

But, as @jxself is saying here, Firefox will survive in some form or other.

We've seen this all before, when Oracle put OpenOffice into its death throes and The Document Foundation and LibreOffice rose from its ashes and greatly improved on the suite of programs. The free software development model is very adaptive in that way - like water flowing around obstacles. Who knows - Firefox could become much better if taken out from under Mozilla.
