> As far as I can tell the result met the needs of the business? They have burnt their bridges by making it impossible to revert to older version. In effect, if someone can not run a newer version, they will be forced to completely abandon the software. Of course, that still counts as "meeting needs of the business" if the only thing your business needs is surviving for a couple more days. But that can be accomplished a lot more easily by doing nothing — your business is unlikely to vanish in puff of smoke tomorrow, as long as you simply sit on your hands. IMO, they could have halted distribution of buggy newer version, released minor fix for older one to stop it from crashing, then finally a backwards-compatible major release. That's more or less same effort, but with less damage to reputation and users of software.
