They ship 32-bit versions still to support those people. As a former msft engineer it was a huge pain in the ass to have to build the 32-bit version all the time - but customers used and relied on it.
I have it installed on an old 2006 MacBook, so Microsoft was still providing updates for a 12 year old machine... one that Apple itself abandoned after just 6 years. It's one of my favorite examples of Microsoft's longer support for old hardware.
And for what it's worth, after 12 years and 3 Mac purchases, I've switched & just bought a PC again.
