Yes, which is why the EU’s recent legislation is a terrible, terrible thing. The People’s cry for other rendering engines on iOS is a sham (the free market chose iOS among other, more permissive and equally viable platforms). Real people don’t care, and real people won’t notice because they do not care what rendering engine is powering their browser. They only care that websites work and that browsers provide the features they expect. But thanks to the EU, the death of non-Chromium browsers just accelerated to the benefit of no real person. Mozilla will of course continue to make nice browser features, but the day will come when a blog post details their reasons for ditching Gecko. Real people won’t notice and the industry will have further reduced (read: eliminated) engine diversity - the very thing EU was trying to avoid.
