They are not taking anything limited from anybody, they're making it accessible for everybody else that didn't get to preorder Endwalker back in 2021. It's not rare, it's quite literally a very small thing, and people who wanted it can now get it.
You didn't have to work for it in game to earn it either, you just had to preorder EW during that period. It's not an accomplishment. I don't think scarcity on an earring from 4 years ago is worth getting upset for.
It absolutely does matter actually. All it does is giving you an XP buff that stops at level 80. Not even 90+, 80. Aside from the original design, it absolutely is an outdated item. On top of that, it encourages players not to use leveling/story skips and actually play and access the content faster. There is no negatives to this.
