@Me ok, I guess I'll out myself as boomer AF, but I do remember what it felt like to use Windows in the 90s, and the 2001 United Stats vs Microsoft lawsuit, and no, it was more than just "packed their own in". Manufacturers were specifically prohibited from putting any other browser icon on the default desktop than IE. And back then Windows was so integrated with IE that Microsoft actually thought it was a **benefit** to prove in court just how parasitic the browser was.
And finally, the case revealed all the ways Microsoft abused their monopoly power and pressured Netscape to stop developing Navigator, actively withheld the APIs needed to release with Windows 95. The story repeats with Sun Java, Apple, Lotus, Linux, etc. Obviously Windows on the customer-facing side didn't explicitly prohibit the installation and use of the software, but just one step into the background and it was pretty clear that every action taken was to manipulate the situation to be just that.
