The big issue is that by adding more and more features, a browser has become an operating system and so complex that you can’t hope to make a new one from scratch.
The last “new” browser engine (that wasn’t built by a corporation) was KHTML which was stolen harvested first by Apple for Webkit and subsequently by Google for Blink. KHTML then rotted without support.
The most recent attempt was to build Servo in Rust. Mozilla “ran out of money” (they depend on Google for their existence), and it’s already rotting.
I didn’t mean to suggest that. Simply that he was a business man doing business in a capitalist society. If you lose the talent of your main chef, what do you do? You ride his name and legacy for as long as you can.
I never figured out why, but I couldn’t get any version of suse to work properly on my computers. I’ve been with Debian (sid) for about a decade now, so not the most up to date criticism here.
