People who didn't live through that era really don't appreciate a key aspect of it, which was that MSFT OWNED the desktop -- like, 90+% of the market. There were no other real options. For a good chunk of that period, Apple was seriously on the ropes and might not have survived. (Michael Dell famously said it should be sold off and the money returned to the investors.)
Microsoft had deals in place with PC makers so that it was impossible, nearly, to buy a computer without buying a Windows license. BillG specifically told Netscape he planned to "cut off their oxygen supply" by shipping a browser with Windows, and he did this because he was smart enough to see that browser-based software could endanger their control of computing. That was literally illegal.
No one has anything like the control they had back then. The desktop market is still mostly Windows, but Apple got healthy and took a decent chunk back. Now there's also ChromeOS and Linux out there, too -- plus, we have mobile, which is an even BIGGER chunk of the platform market, and it's split between iOS and Android.
So that's at least 6 different software platforms a hypothetical user could pick in 2022, and they're spread over dozens of hardware manufacturers. That's been the norm for so long now that it's easy to forget how little choice we had in 1998.
*ANYWAY* the bigger point is that adding features to your system isn't a problem if you're not acting as a monopolist. Microsoft WAS in the 90s. Nobody has that ability now.
