The Mac could write Microsoft compatible documents before Windows even existed. Word was released for Mac in 1985.
Additionally Office file formats were documented before the anti-trust trial. The consent decree required Microsoft to document various APIs, which are quite different from file formats. Apples growth had nothing to do with the ability to read Microsoft office documents, it had to do with the success of the smartphone, an area that Microsoft never had broad success in anyway.
It was the newer file types in 1998/2000-era that had to be opened as well, which wasn’t part of prior deals. This was a new file type they made when trying to “close up” and grab hold of the Windows Desktop+Office bundle (another monopoly point). The DOJ consent decree created a vacuum where Microsoft couldn’t move or do anything for 10 years due to judicial oversight. That’s why when they bought Skype, they did nothing with it. They couldn’t integrate it with (then) office communicator (which begat Live communicator which begat Lync). The couldn’t expand Windows Mobile either. Which was the smartphone vacuum leading to the iPhone.
Even all the OEM deals were DOJ-reviewed. Everything they did was DOJ-reviewed first. They had to ask to fart. There was an inside story about the Skype acquisition. It was quite a fuss internally.
They could work on something almost entirely new, tho, which they did in the far far background (Ray Ozzy’s project). That project became Azure once the decree expired in 2008/2009-ish. By then, the iPhone was here, iPad was imminent, iPod was still a rage, Mac was a real thing, and Internet Explorer was starved. Google happened, Amazon expanded beyond “just books” (yes, kids, Amazon originally only sold books, not guitar strings and pottery and toys), AWS and Netflix happened, and we had a functioning market again.
The consent decree was stronger than most people realized. Microsoft avoided being broken apart, which most people wanted (revenge, like with ATT and SO), but breaking them probably would’ve made Microsoft stronger. IIRC judge gave them a choice, break up or submit to DOJ oversight; they chose the oversight. Keeping them as a starving giant was the right call. Tough to make back in 1999 when “revenge” was on everyone’s mind.
Wow, tho... still hard to imagine it even now and looking back on that time. A lot really did change. Palm died, Nokia died, blackberry died, Sony’s mobile thing died... all these hitched themselves to Microsoft’s wagon. Yeah Palm had their own thing but they tried to compete in a largely Windows Mobile world, then starved, and couldn’t come back. None of these could innovate either because they relied on Microsoft to source the mobile OS code. It was all the same base line crap; very little differentiation. Ripe for disruption. Ergo, the iPhone.
Good times.... 😆
