There is one thing I don't understand from the article. What is that he is so afraid of?that the website becomes more standarized and developers don't need to make a website for 5 different browsers? Or that because of that users will have less problems? Is that such a big deal to make most of the browsers dependent on chromium? Isn't chromium open source and tomorrow anyone could create a better browser? I use Vivaldi, can't be happier.... Some people seem to be worry about a lot of stuff
As someone who lived through the previous browser monopoly (MSIE), let me assure you that giving control over the entire web to one company is bad for everyone. Google didn't make Chrome out of the goodness of their hearts.
"Chromium would likely die if Google abandoned it."
I believe that is highly unlikely. At root the Blink engine is actively supported by several big tech heavyweights. Microsoft Edge is based on it. A rarely mentioned but important derivative browser is Silk (Fire tablets etc.) that Amazon develops. Then there are a bunch of smaller fish with Brave leading that pack.
I think the engine would survive just fine without Google. There was a time when you're view held, but that time has past.
