Yes, because before Chrome existed most people used IE which is very slow to create or adopt new web standards and is full of bugs. That makes developing complex websites really difficult.
What company do we know that makes some the most complex web sites out there and would really benefit if the web had... I dunno WebGL so they could make a smooth mapping site, maybe with a 3D mode. Or a new version of HTTP so their sites load faster. Or a new version of TCP that works better on mobile. Or native web components that makes their web framework faster. Or HTML video so their video streaming site is more reliable.
I'll give you a hint - it starts with "Googl".
They created Chrome because IE was holding them back. Not to kill as blockers (did IE ever even support as blockers). Some people here don't use their brains...
Reality was a bit different from what you describe. Firefox was a thing. Its market share was rising slowly but steadily. Google paid leading Firefox engineers such as Ben Goodger and Darin Fisher. It could have doubled down, improved Firefox's performance, marketed it aggressively, and then your narrative would make sense. Instead they pulled the engineers to create Chrome. There was no need at all for that except that Google wanted more direct control over the Internet which the nonprofit Mozilla Foundation ultimately wouldn't give them.
That nobody would do that is contradicted by the fact that Google did it for years, for instance. But Google ended up doing what most for-profit corporations would do. I'm not saying it's particularly immoral. It's pretty normal, for better or worse. What I am saying is that the narrative that Google created Chrome only to further the Web does not add up.
Also, I was not ignoring that IE had 60% market share. That's perfectly in line with what I said, as that market share was in fact shrinking without Chrome.
So, to be clear, you are saying they were being altruistic and purely motivated by the desire to push forward web standards, and that this is entirely unrelated to the business they run?
