I think this is definitely some weird attempt to justify a terrible piece of technological junk....

For all the hate people gave CSS, it was/is fantastic at its job. Word documents are an example of how you don't design a document, and how when a for profit org designs a thing (instead of standards and market pressures), you get a technological monstrosity...

To be clear, I don't think LibreOffice is great. Part of their issue, they were built as a way to "not pay" for office, and it turns out that no, volunteers don't really do a better job at implementing 1000 pages of nonsense that the people who came up with that spaghetti code in the first place...

We don't need that software anymore, though. If you use it, know we are looking at you like you are pulling out a physical paper phonebook to store your numbers in, or a less hurtfully but just as topically, a record or CD player...it is dinosaur technology that pretty much has no place in todays world...

So, they have a point, I don't disagree with them, however it probably would be better just to "admit defeat", get MS to open source their code for compat reasons, and work on something new that's not trying to write viruses on your computer better than paragraphs...
