The reason this matters should be obvious. Scroll through this thread and see how often somebody is posting about how the pre-orders are killing them. That's because of the understandable belief that, if they don't pre-order something immediately, it could be too late for them to ever own it. That's how these "limited" releases wind up with 600 variants and so many customers wind up purchasing something they didn't end up wanting, because they didn't know what was coming next. To advertise something as limited pushes it higher up the FOMO/priority list. So, to deceive your customer base isn't just about tricking them into thinking what they got was extra "special" or "valuable," it directly influences their spending habits and, when they have compulsive tendencies, gets them to spend money that they otherwise might not have, and/or spend money at less responsible times for them financially. Beyond that, it forces people who would be less interested into "taking a chance" on something they either have never heard of, or are only moderately interested in, for fear they might be missing something. Once they have it, you've inadvertently put a title into someone's hands that has resale value and that they don't necessarily want after all.
If it's limited, that's cool. I get that angle feels almost necessary to companies that weren't selling much vinyl and were simply trying to stay in business before all of this culture took a shift. If everything else is limited and yours isn't, then you're falling back on that priority list for purchases. But, it's like a game of double dutch now trying to jump into these ropes, and that's for everyone from the retailers and labels to the customers. If they announce something as limited, it should be. If it's not, then it's false advertisement and it's still a deceptive practice, at best.
