One thing I haven't seen mentioned: Chrome OS. I have two Chrome OS devices that are useless without adblock. They can't handle the real internet. And who would want to buy a Chrome OS device that could?
My Chromebox is my most used computer in my house (it powers the living room TV) so this'll be a real inconvenience for my family.
Newer versions of Chrome OS are able to run Linux in a container. You can install Firefox with the "firefox-esr" package in that Linux. Unfortunately, audio doesn't work yet (at least not on my PixelBook), so it's not really a complete solution, but for (quiet) browsing it does work with uBlock Origin. Apparently Linux audio under Chrome OS is coming soon.
