I can agree with this. To me, a computer being able to display a website, in 2020, is basic functionality. Something my phone and refrigirator can do is something a full blown computer should be able to do out of the box. For an os that includes basic photo editing software, hypertext editing, video and music players, and game system integration, displaying a webpage is a basic tool. Just like a basic toolset from lowes is expected to have a screwdriver.
I think you are defining a computer OS as a basic OS -like TRON on a microwave. It is not -it's a multi-GB platform, and a basic tool included in it is not a basic tool you'd expect from a microwave. But these days, some microwaves also include a browser.
Much like airbags are a basic safety feature, but were not 20 years ago. Much like vi was a basic feature. But why include vi, when all you need is ed?
