Webkit and Chromium have their infancy in Europe. It started off in many ways in a building where Opera and Trolltech resided. There is a lot of history there, which takes longer to explain, but I think a strong Vivaldi, based on Chromium, can make a big difference. I say that based on my experience fighting Big Tech over more than 32 years now.
