Ok, well sure, when used to advertise an item for sale it is a "buzzword." Like "vintage," or "rare," or "Arnold Palmer and Dave Mustaine Collaborative Limited Edition!"... or "factory original?"
Unless you're actually dealing in commodities, you look for ways to make your item stand out from all the others for sale. Value is whatever someone will pay -- not a penny more or a penny less. You've got to get someone to choose yours. Not all sales jargon is equally effective, of course.
Well, the job of every seller is to convince someone to pay the most possible for his item. The job of every buyer is to negotiate the lowest price for the highest value. That does make sales inherently adversarial, no matter how cordial.
Fortunately, no one can demand you pay a penny for anything. Likewise, you can't demand they part with it for a penny less than they want for it. But it does make some folks angry to see things offered for sale at more than they would pay for them, and it makes some folks very angry to be told that someone doesn't value their sale items as highly as they do themselves. Lots of anger in the world. Outrage where it isn't actually appropriate. You don't like the changes I've made? You don't agree that this is "customized?" You (ah HA...the true root of the matter) don't want to pay what I want to be paid to part with it? Fine. No sale takes place, peace be upon you, good luck in your search!
All judgment calls with no actual grounding in fact. Opinion is a fine reason to decide not to buy something. But a little buzzer bell on the handlebar makes some riders pretty happy. It's all good!
