I watched the archived livestream last night. I thought Pete's explanation of the problem was clear, but I'm still not sure why something couldn't be implemented (as per Gregory's suggestions above) to make changes and allow users to accept them so we wouldn't have to settle for (and compound) past errors and inconsistencies. I completely understand not wanting to make users move all their inventory after a title correction--I don't want to do that! But can't it be automated, with an option to decline for those with a reason to do so? Their titles would then stand out as "unrecognized" after updates, but currently my titles stand out as unrecognized if I correct them.
It seems somewhat analogous to the problem with OneDrive, which is something else that caused me a lot of grief. I eventually got it sorted out, but I spent a few hours going through the information, figuring out what to do, and fighting OneDrive to straighten it all out on my system. (It sounded simpler than it was.) The OneDrive situation was problematic for enough users that they've now devised a way for ComicBase to handle the move as long as you accept the action presented in a dialog box. That would have saved me some grief. Couldn't title and series corrections be handled with a similar approach? Display a dialog box and let the user decide if they want ComicBase to take action for them?
From a technological view, the inability to correct titles in software designed for organization (without causing a lot of headaches for users) is a bug that should be fixed. From an archival view, the inclusion and perpetuation of inaccurate information is a strike against the product's credibility. From a capitalistic view, information presented incorrectly or inconsistently sometimes makes buying and selling more difficult, because you can't buy what you can't find. There are multiple good reasons to find a solution to this problem. It doesn't reflect well on an otherwise great product.
