Ever tried it?
Ever tried reporting a bug to a Commerical software company? Critical or otherwise. They don't like it, at least not in my experience.
I tracked down a bug in my mobile phone's software. I isolated the cause and the consequences and with a coherent bug report I called them up to report it. I was told it was my fault for using the handset in that way even though it was a pretty standard thing I was trying to do, and we're not talking about some rooted smart phone here either.
Add to that all the times I've tried to report problems in the way Yahoo mail (I know bugs in Y! mail is like shooting fish in a barrel) parses and forwards HTML emails. I've received a reply once from several detailed bug reports (not just "It don't work") and was told to just reload the page or some BS.
In contrast when I've found bugs in free software the dev has usually been really interested in getting the problems solved. Most recently an app on my Android phone had problems and the dev couldn't have been more helpful. Within a couple of weeks the problems were all solved. For a free app I can't complain about that kind of service!
If commercial companies had any interest in receiving the bug reports (from me or the earlier correspondent) may be we'd bother in the first place. Perhaps they could learn a lesson from the "freetards" out there who give a damn about their users!
