If I use my own family as an example:
My wife spends all her time at her computer in Microsoft Edge (she has a Mac and Safari doesn't work properly with a load of sites she uses)
My son only plays games on his Switch and when he gets a computer next year, I'd bet it will be for surfing the web and playing streaming games
My mum and dad only use the browser on the Windows PC they have (and the iPad too)
My use case involves dev work and uni work so I can't use a Chromebook.
People want zero-friction. If they can open a browser, or better, click a link at the bottom on the taskbar that opens their "application" then they don't care what's behind it.
Chromebooks definitely have their place... that being said, Google's customer service leaves a lot to be desired and putting all your eggs in that basket is a risky proposition.
With the mere action of including lxc in it later, it shows how much full functionality is wanted in such a device. But it's ass-backwards now.
I completely understand wanting to have more capabilities on these Chromebooks though. I ran elementaryOS on an HP Chromebook for many years and it was amazing for the price. A great battery life, good keyboard and touchpad and a full blown OS that is also lightweight and snappy. But I think that the annoying thing is that the same hardware isn't sold by the manufacturer without ChromeOS.
Was a Chromebook the only workable solution? No, of course not. Having _something_ was a huge advantage over hoping the library would be open some time you weren't in class or working (a tenuous proposition, especially near weekends or anything that might be misconstrued as a holiday), and in that price bracket there was no competition that came close to a Chromebook.
I don't think the average user cares, as long as they can do what they need to do. See https://www.youtube.com/watch?v=o4MwTvtyrUQ
Microsoft tried that with IE, and got sued. They ended up having to add a 'carousel' of alternate browser options during a users first login.
Guessing no-one wants to tempt fate like that again.
