Not close to just dotfiles of Arch. It used to be that, sure. That was a year ago. Now they have their own packaging infrastructure going on, both different stages of Arch mirrors (stable is a ~month behind Arch to catch buggy packages and supply chain attacks) and run their own extra repository for other software. The Omarchy stuff isn't dotfiles, it's proper packages served by their own infrastructure nowadays.
Brave has a tipping service that lets users tip creators with Brave's crypto coin, BAT. When they launched the tipping service, they put out a pool of their own BAT and let users tip with that BAT. Their initial UI for the tipping app was sadly bad, and didn't really properly show which creators were signed up for the program, which weren't. If the tips from the pool were given to someone not on the program, Brave would hold them assigned to that person for 30 days, then return them to the pool. No user's resources were affected.
Tom Scott gave them some harsh criticism for the UI, and Brave improved it within a couple days, resolving Scott's complaints.
Mozilla wants to do quite a lot more than just make a browser - for years, under Mitchell Baker, they weren't really primarily browser makers even. After she's left, Firefox has gained a new degree of focus and we've actually gotten good new features.
Also Firefox is made by Mozilla Corporation, and they're funded by Google money. Firefox defaults to Google search and search suggestions on, which is an awful privacy posture.
Brave's an easy slot-in - fiddle with settings or buy Brave Origin, and you get what's basically Chrome, except it has a built-in ad blocker that can do stuff extension-based ad blockers (even MV2 ones) can't do on Chromium, the profile sync backend is end to end encrypted, and you get ~uBO grade adblock on mobile.
A chief benefit is that Chromium is much more secure than Firefox, especially on mobile.
Chat control was shot down, and will be proposed again. And again. And again. Until the people/governments vote correctly, and then dismantling it won't be up for a constant vote.
Cyan isn't between green and blue, at least not completely. If you take green and blue, you won't be able to represent a good chunk of cyan hues. It feels greenish and blueish, but is neither, and is broader than any combination of the two, which is partly why some bright cyan objects (like the bird eggs on Wikipedia) look kind of unnaturally intense. Those eggs are a bright, slightly blue-leaning cyan.
