alt Hacker News> Why not outrage over their choice of Windows itself?
Because it doesn't necessarily affect anyone. Using Windows ipso facto doesn't mean you will send someone a file they can't read without a Microsoft program.
I have two Windows machines in my home; they have LibreOffice on them, as well as Firefox.
No, but I think the people most likely to be oblivious to all this, will be the ones using Microsoft programs that write in proprietary formats by default... and I would say they're not even wrong if that's what most other people use too.
People send me Outlook messages all the time that I can't read at all, and many Excel spreadsheets and Powerpoint presentations with features that aren't supported in anything on Linux. I literally have to use a Windows VM with proper Office to read this stuff. And not only work documents, but documents from my children's school/teachers as well.
