First, Chrome won the browser war fair and square by building a better surfboard for the internet
.
No, it 100% did not. Let's take the Ruby founder taking some technical appreciation for the improvements of Chrome (despite other issues).
Beyond Google and Google services heavily positioning Chrome installs, other freeware like Flash, Shockwave, Java, CCleaner would promote Chrome, because you'd get paid up to $1 per install. Software that did this would sometimes alternate based on either existing install or keeping other people on their toes installing other software like the Ask.com toolbar or "McAfee Security Scan Plus". This helped convert technically illiterate users who were pushed into what their trusted site told them was the best, or what they either trusted or clicked through on a shrinkwrap installer.
Secondly, Google has a history of using Chrome specific quirks to make other browsers behave worse. Like using deprecated Shadow DOM v0 calls only ever implemented in Chrome/Chromium derivatives that loaded 5x worse in alternative browsers like Firefox that weren't Chrome based.
Google now lets to define the web standards that succeed or fail by overwhelming marketshare. It is the same behavior that led the Justice Department to declare IE monopolistic, even though the origin market differed by company (Microsoft by desktop OS, Google by internet advertising/services), the end result of the tying is the same - one monopoly supporting the other to the detriment of the entire web.
The ManifestV3 force and Manifest V2 deprecation that deprecates much more effective privacy/ad blockers used under ManifestV2 is a prime example of Google using their dominant browser position to preserve their ad business.
A budget is just a method of worrying before you spend money, as well as afterward.
