1. Including a free competitor in a hot new market
2. Threatening hardware OEMs with financial penalties (not getting OEM copies of Windows) if they continued the practice of bundling the primary player's product (Netscape)
Back then, Web browsers were something you went to a brick and mortar store and paid good money for a disk to get. They weren't just handed out for free online. Microsoft flattened the competition in a market they were not previously in by leveraging their dominance in another market.
Who did that? You could just grab an installer for netscape over FTP, IE came on every windows system by default, and if you really wanted a CD or floppy with a browser on it, your ISP would send you one. AOL CDs were sent to every mailbox in the country repeatedly and totally unsolicited and those contained browser installers. Nobody I've ever known went running to the store to buy a web browser and I know people who paid for pkzip
As a person who was on the internet since 1993, they were? Maybe if you wanted Netscape Gold with the editor, but I never paid for a browser and never remember any prompts urging me to do so or having to reinstall a shareware copy of anything.
Don't get me wrong, I'm all in favor of enacting laws to protect freedom on the web platform. But the Microsoft fact pattern just doesn't apply.
It applies to Google through Android. Amazon sells a Fire TV, which uses AOSP; but now Google's licensing forbids Amazon from also offering an Android TV product.
Perhaps Apple should face antitrust action, perhaps not, but the MS ruling doesn't really apply as Apple does not license their software. The ruling was meant to empower OEMs and Apple IS the OEM.
Operating Systems didn't always come with a browser. We used to have to go to a store and buy copies on floppy disk or get a copy from a friend or download from a BBS. Hell, sometimes we had to install TCP/IP support since it wasn't part of the OS. So when MS included a browser in Windows the groups that also made browsers cried foul. Downloading and installing software was a painful thing and a real barrier to adoption.
