I don't know what the situation is on Microsoft Windows, but these requests that are being asked are mostly already applied on iOS:

We call on Microsoft to respect its users and implement the following changes immediately and on a worldwide basis:

-Allow browser suppliers to compete for preinstallation and default deals with Windows PC manufacturers.

-End dark patterns targeted at users seeking to download and effectively use other browsers (including as system level default).

-Bring back the ability for users to make switching default browsers simple and transparent with a “single click” change for all relevant file types and apps (including PDFs).

-Open all web links in users’ selected system-level browser of choice.

-Eliminate manipulative Microsoft-exclusive banners pushing Edge in Windows, including when users are searching for other browsers.

-Stop using operating system updates to push users back to Edge.

-Remove the restrictive configurations of existing S mode devices that block usage of third-party browsers
