Google can Set Standards to their own Advantage, e.g. with regards to Tracking which reinforces their Monopoly on Things Like Ads, the Same reason they crippled all the AdBlockers with ManifestV3 on Chromium-based Browsers
And the only alternative that isn’t Chromium-based is Firefox. (Or Safari with WebKit). All other Browsers use Chromium
So it would be really good for everyone if they were forced to sell Chrome
No, not every company can afford to Bulldoze the competition in the Browser Market because they have indefinite deep pockets from the Ad Business.
If that unfair advantage goes away there will be more competition again in the Browser Segment .
Also Marketshare can grow and shrink quick
