When something that used to work no longer does so.
One can claim that the product is now different and that you can't compare the old product with the new one (that conveniently uses the old product's name), but to the person thinking that they're getting an update of the same thing, it's a step backwards.
This means that when we try and put a modern distribution in front of people, instead of explaining how it is mostly the same (and thus what they are used to themselves) but better, we now have to explain why it is different and things that used to work no longer do so.
Frequent blog posts by people pretending to be brand strategists and visionaries don't actually placate user concerns because the users are mostly concerned with whether stuff does what they need it to, not whether the "positioning" of the software is right according to current market trends, or whatever.
After all, no amount of blogging can make something work again or even work in the first place.
