It's an entirely legitimate concern. But the fault that causes this worry is fundamentally a lack of openess. The solution is to promote openness. To be exact, if the document format was open then there wouldn't be a problem, or at least many orders of magnitude less of a problem.

End users shouldn't have to worry about this because the techies should have figured it out for them. Not only have we failed, there's a bunch of comments here that show that we (techies, as a class) don't even understand the problem.
