Which is so weird, because office is crapware. It’s terrible software.
If so then all the other offerings are even worse crapware.
In my experience Microsoft Office opens twice as fast reliably than LibreOffice (when I terminate the process responsible for keeping it ready it takes about the same amount of time but it's no slower importantly).
Microsoft office is simply the best. It's a fact. It can do tons of things that Libreoffice and OpenOffice cannot. It has tons of advanced features, it's just a superior office suite.
Comparing LibreOffice to Microsoft Office is like comparing a Lexus SUV with the full package of options installed compared to a basic fleet Ford sedan. Yes both can do very basic things and if you just need to type some things or do very basic spreadsheets then they're interchangeable.
But ask some slightly advanced things like sortable tables (Excel does easily) and suddenly only MS office can do that and the LibreOffice people tell you to pound sand and use a database which doesn't make sense for a lot of tasks when you may just be preparing some data for example for a presentation or some quick financial work (I'm talking about stuff for myself, not a professional accountant), etc. Take a look at design options in MS Word compared to LibreOffice writer. Both have title and header styling options but the MS office ones simply look more professional, cleaner, and they have more options you can easily tweak. If I'm presenting a report I absolutely want to do it in MS office because I can make it look neater and nicer with less effort.
Businesses use it because 1) they're used to using it, it's a standard among businesses and the public, and it's maximally compatible with files created by it so interoperability isn't an issue as long as you too use it, 2) it's the best. It has more options than others, it can do more things. It has more depth. It has extensive support and documentation and it has good integration between the different pieces of software.
It's like comparing GIMP to Photoshop. Sorry. I think FOSS is a great philosophy and I hate Microsoft and Adobe as much as anyone but in practice Photoshop is miles and miles beyond GIMP in capabilities. And this is coming from someone who has GIMP installed and not Photoshop (because PS is expensive).
The extended suite of MS office has always been meh. But it doesn't matter. Word, Excel, PowerPoint all work great and are exceptional tools at the top of their class. Could they be better? Yes. But they don't have to be the best possible, they just have to be the best compared to other offerings by a country mile and they are if your needs are any more complex than the occasional letter to grandma.
Does that mean I think people should pay for MS Office? Not when there are ways to get it free with no cracking or risk.
My problem with this in spite of the dire situation they face if Google is forced to cut funding by anti-trust court rulings (or not even forced but they make paying off Mozilla a moot point so they stop) is that they become an ad company. Ads become tied to their CEO compensation, to the salaries of the people who develop it.
They claim they're making a better kind of ad network, a privacy respecting kind. The problem is the ad industry doesn't want less data, they want more. There are no looming laws that would force the ad industry to adopt a more privacy respecting alternative or die and without that the ad industry is going to shun this and it'll be a failure and then they'll have a failed ad network that they can either discard entirely or adapt to industry standards of privacy invasion and abuse and continue to exist and then they'll make another "hard choices" post about having to do that.
And I can see it now. This experiment will fail and after some pressure from the ad industry and some devil-on-shoulder whispering Mozilla will begrudgingly start to enshittify. Their ad network will become less privacy respecting by tiny little steps, by salami-slicing or boiling the frog, the whole privacy-preserving measurement thing will be thrown out BUT they'll still claim they respect you more than Google and will at first perhaps but that will erode. Maybe they'll just implode at some point after that which given Google is being found a monopoly works just fine for Google and the rest of big tech who want a more centralized, locked down browser company that wants to help implement DRM that can't be circumvented, that wants to help lock down everything on the web to restrict users freedoms to choose what is displayed or if they can save it or record it or copy it to say nothing of blocking ads.
