> the problem is network effects

This is absolutely the problem - with the added issue of platform support.

I’m the only Mac user in our company of 15, which means I’m also the only person that can open a .pages file. Anyone can read a .docx, and if authored in word it will actually look the same on both computers.

Is it 2% who author content using those tools, or are you also including anyone who might need to open and use a spreadsheet using one of those technologies?
