Sorry you feel that way, but it wasn't a knee-jerk reaction. I don't expect anyone with your attitude to understand though, but I'll explain anyway. The decision to switch over from vBulletin to XenForo was made a very long time ago, the vBulletin vulnerability (which has not been patched, and also affects vBulletin 5, and has only been called
a "potential exploit" by Internet Brands) was just too much for us to stay with something we already had planned to migrate from.
