Nobody wants to use Microsoft specifically. But that's what they're used to. And that's what the industry standard is. LibreOffice does not prioritize compatibility with Microsoft Office formats. LibreOffice has tabbed mode which feels a bit more like "home", but for some reason is missing options on this Ui view.

That's why people are interested. If it looks exactly like Microsoft Office and is 100% compatible with Microsoft Office formats without having to use a Microsoft product, that is a win. Will it be possible to maintain since it was so heavily vibe coded? That remains to be seen. But let's not pretend that open source projects are just as good or better in every way. LibreOffice is a lot closer than most, but Gimp is no Photoshop, for example, and after 30 years of waiting, I think it's safe to say that it's not gonna be. As much as I respect both LibreOffice and Gimp.
