I went through most of the comment and something I thought hasn't been mentioned yet.
May be those product should not have been built with Javascript in the first place?
I remember when Chrome OS was launched, people like the blog post author were all over it. It was the future!. And I was surprised he was an Apple user. I thought Apple users cared way more, and way beyond some high level abstraction convenience at the expense of quality.
I have been working with dozens if not hundreds of companies, and none of them use Google Sheet for anything serious. It is on Excel, and if it is on the web the trend is now Excel 365.
If you demand quality, there isn't even a single App built with Web Technology that is A Class. This may change when WASM is a thing. But for now there is simply no replacement.
Lots of educations were initially switching to ChromeOS and Google. They later switched back to iPad. Why is that? There is something about Google and ChromeOS's quality that is not up to standard. And the users knows it, they just couldn't explain it. But it was crap, at least compare it to their iPad. And it has performance hit on its user. Because they were not satisfied.
This isn't to say ChromeOS cant be Good. But Google, generally speaking has absolutely no taste on quality. They are even worst than Microsoft. In Microsoft you could still see a glimpse of product person fighting with ( sorry HN ) idiotic geeks solution and then came out with a compromise. And MS Product person isn't anywhere as good as Apple's in the first place. But you see ZERO User product design in Google. It is as if a product is designed by geeks, built by geeks, marketed by geeks, and feed into their own echo chamber how great it is.
And Android now is no different to Windows in the 90s.
I never took a serious look into Google's financial, but I am surprised they are a trillion dollar company while Apple is only worst 50% more.
