Fuck Chromium (and that includes Brave and Vivialdi)
I have made multiple posts about why you should use Firefox, and of course I get the reply "not all chromium browsers are bad, they are not all as evil as Chrome." And sure, browsers who use the chromium code are not required to do all the shady things that Google does with it.
Still, I think it's bad that chromium-based browsers are getting close to total market dominance. By this point it has made Google's competitors like Microsoft and Opera drop their own unique proprietary browser engines for chromium. Browsers are becoming a fucking monoculture at this point. And Chromium becoming the browser code base of choice empowers Google, since they are the ones who mainly develop, maintain and fund its code. It means supporting them in their quest to become an internet monopoly that can do things like drm the web itself.
So let me be clear: you are still supporting google by using chromium-based browsers. By helping out in making chromium the de facto standard for browsers, you are giving google power. They are the ones driving chromium development, they will set the standards. And those standards will be in Google's favor. They are an ad company, their goal is to kill off adblockers by making them impossible to use, first with manifest v3 for extensions and now WEI, their web drm.
The supposed "good guy" chromium browsers people recommend are actually shady as shit.
The one i see recommended the most is Brave, and it's fucking terrible. For one thing, it is funded by right-wing techbro Brendan Eich. He was Mozilla CEO for some time, but then people found he was a massive homophobe who funded campaigns against marriage equality, and Mozilla forced him to resign. And that's why he created Brave. That's who you are supporting by using Brave.
It runs off chromium because that's the easy and lazy choice for a browser. And it's literally funded through cryptocurrency, probably the negative environmental impact is a plus in Eich's book. And its adblocker runs off the same dishonest business model as adblock plus does, it will not block ads if advertisers pay them for the privilege. This betrayal of the users is opt-in at least, and you get paid for watching ads, but it's in the aforementioned worthless crypto beans. Brave is a joke.
Vivaldi and the importance of open-source
And then there's Vivaldi, it's a freeware proprietary browser run by a for-profit company, which alone should scare you off it.
"If you aren't paying for it, you are not the customer, you are the product" is a phrase that sometimes unfairly gets applied to open source projects to dismiss them. If it's open source and either community-run or run by a non-profit foundation like the Open document foundation for Libreoffice and or the Mozilla foundation for Firefox/Thunderbird, you are safe even if it's free.
But that phrase 100% applies to free products from for-profit corporations. These companies need to make profits at some point for for their shareholders, and if it is not from selling goods or services, it comes from things like selling your user's data or "attention".
That applies to Vivaldi, who makes big promises about how they will respect their users privacy and never sell their data. But promises mean nothing, Google also says they respect your privacy. And the thing is, Vivaldi is closed source. Not entirely, ironically the bits they got from Google's chromium are open source, but other parts of their code is closed-source. And what that means is, they can make any and all promises about what their browser's code does and there is nobody except Vivaldi that can check if their code actually fulfils those promises. Only Vivaldi has access to that code.
I'm no open-source fanatic, like I don't care if some random game i install and play is closed-source, as long as it is from a credible developer. But open-source is important for security and privacy, because that means someone else other than the company who develops the program can vet it's code for vulnerabilities and privacy violations. Your browser and e-mail client (vivaldi has an e-mail client too) should be open-source for your own safety, because those programs handle sensitive data like your passwords or your e-mails. Closed-source is not more secure, since Kerckhoff's principle applies to digital security and privacy.
And Vivaldi by being proprietary software fails that test. Their own justification is that being closed-source is "their first line of defense, to prevent other parties from taking the code and building an equivalent browser (essentially a fork) too easily." It's the same hypocritical argument that Red Hat used to justify making their Enterprise Linux distro closed-source. "It's fine if we use chromium's code to build our own browser, and expressly for making an Opera clone (that's the literal point of Vivaldi, that's why the name is a music reference), but if someone does the same with our product, they're evil." It's nauseating and alone justification to distrust Vivaldi as it is crying out to be trusted.
Listen to some Antonio Vivaldi instead, his music slaps. And install Firefox and Thunderbird instead.
