Pfft, proprietary propaganda. How hard is it to let go of every app you’re familiar with, learn half a dozen scripting languages, and memorize a hundred different commands in vim?
What you say is true, though I’ve become so jaded with Microsoft that I don’t think there’s any software or situation I’d use Windows for; I’d sooner switch to Mac.
To each their own. Personally I can’t stand MS Office, I think Google Docs is easier for most nontechnical people these days anyway. For the rare cases when Office is needed, the web version works fine on Linux.
LibreOffice works great, and WPS Office is proprietary but at least it’s free.
Personally I write my documents in markdown and use pandoc to convert them into PDF or docx or whatever. It’s like writing the source code and then compiling, I like it.
I’m sure you’ve looked into all that, but for anyone else who is interested in alternatives those are my recommendations.
