I would say it was less of a culture and much more of a marketing/lock-in strategy that worked extremely well for decades. Firstly by being the most popular windowing environment that still ran MS-DOS apps, then being the only windowing game in town when they rug-pulled OS/2. That consolidation enabled Office to become dominant and that compatibility took over as the cudgel to keep the world locked to Windows.
Microsoft, for the first time, is betting against their own OS with the web version of Office. I can rent Office on a monthly basis and run whatever OS I please to access it (mostly). But if I no longer absolutely have to have an Intel based Windows machine that lock-in has to shift to Office online.
What processor you have will be irrelevent to them, they'll dump native app development as soon as they can because it's no longer part of their bulwark of defences, it's now an encircling trap they need to break out of.
