Cassidy James Blaede, of elementary (and this interview), has an interesting post about the importance of browser diversification, including browser engines.
The web is at its best when there are multiple independent browser engines; that’s when we get competition and innovation. When there is a single dominant browser engine, the company in control of it dictates what can and can’t be done on the web—and developers only target that engine. If you’re old enough, you may remember us being in this position with Internet Explorer for years.
It’s a compelling point. I use Chromium for privacy, but I could switch to Firefox for my main browser. It’s something that’s going on my to do list!
