And paying money to software vendors to bundle Chrome with "Set Chrome as default browser" ticked by default. This is exactly the same thing all the malware browsers and toolbars did in the time period too.
More like having a team of between 1000 and 1500 full time software engineers working on it over a period of more than a decade.
Even if you had 1000 developers who worked for free, you can't get a billion people to care about software quality beyond a certain point.
There is zero difference between firefox and chrome for a layman.
Yes, but also paying for distribution and paying for it to be the default browser.
