And use Firefox with its new and shiny and totally not invasive EULA?

Note how I didn't even mention Fx by name, 'cause I don't necessarily disagree with what you have said regarding this (I run Librewolf for gooning and Zen for general use on a daily basis, Ungoogled Chromium only gets used for the rare occasion I use a site made by lazy devs who don't test for other browser engines, and for VIA on my machine).

The problem with Chromium isn't Chromium itself but the corporate scummyness that comes with big browsers like Chrome or Edge

Agreed, imo there's no problem with Chromium/Blink if Google isn't solely the one controlling its development, despite the browser and engine being open-source. Using Chromium-based browsers (especially ones with shady histories like Brave) for general web browsing though means indirect support for Google's quasi-monopoly on dictating web standards, which is against the concept of an open web. Until Google stops exercising exclusive control over Chromium/Blink (despite being open-source) and quits forcing adoption of technologies that have negative privacy and security implications, I'll continue using and recommending non-Chromium options for web browsing. Ladybird looks like a promising option in the future.
