In the grand scheme of things, it's better for Microsoft that you pirate Office than use something else - so really you are not punishing them for their mistake by doing that.
Your continued use of Office, will mean people can continue sending Office documents and you can send them too, if you used something else that whole system gets disrupted and people you work with consider new tools too. If you share your doc with Google docs for example, their copy of Office for that task is useless and after a while everyone might be using it, in my view it's a much better workflow than email documents around.
Just my 2 cents [I don't think anyone should pirate software by the way].
