How many other software products have entire groups and conferences dedicated to tracking and mitigating the problems they cause? http://www.eusprig.org/
Having problems is not the operative issue. It's userbase. All software has problems; Excel is one of the projects that has a large enough userbase that you can schedule conferences about its problems.
P.S. "EDA" is of course more than one tool, but it's close to the right scope and what jumps to mind right now.
