When did OpenOffice become a shorthand for 'bad usability'?

I mean they're basically just cloning Microsoft Office (There's a joke there but I'll avoid it). I can think of a bunch of problems with OpenOffice but I've never felt they had a particular problem with usability, not compared with Microsoft Office nor with your average Windows or Linux app.

Don't get me wrong there is always room for improvement and they used to do some crazy stuff years back (like have their own desktop) but I'm fairly certain that's in the past.
