What I read from your comment is that youre proud of being stuck in the past. For whatever it's worth (to you, the viability of libreoffice) you're wrong that a multi decade old ui is better than today's.
And the whole "I'm proud of being a curmudgeon " is exactly the problem being identified by others in this thread. It's like you weren't even reading it.
That's incredibly uncharitable interpretation of what the words in the comment say.
Consider this: Word Processing, and Word Processor UX was a solved problem from his perspective 20 years ago (he is far from alone in this opinion). Quite honestly, I have no idea what Word today is doing for me that the Word I was using 2 decades ago wasn't already doing.
It isn't curmudgeonly to say that a product has reached maturity, and does not need changes. This happens a lot outside of the computing realm; a screwdriver from 50 years ago is basically the same as a modern one. A mechanic using his grandfather's screwdriver isn't "proud of being a curmudgeon" they are just using a perfectly good tool that doesn't need updates.
Computers are tools used to achieve end results. The end results desired from a document editor are the same today as they were 30 years ago, and 70 years ago.
Might be, but there is probably a reason other desktop ui features got much wider adoption than that.
I understand millions of people are able to use ms word. I just can't work with the UI. It even makes me angry and aggressive. And that's not an easy thing to achieve.
