As someone who used to work in the games industry, I'm actually not averse to the idea of a cosmetics shop. Selling outfits, mounts, whatever... I'm okay with having people who want to buy that stuff help to further fund the game's development. Heck, I have enough disposable income at this point in my life that I'm happy enough to be that person if there's something I really want.
As others have said, the cost of game development has gone up astronomically; I may not work in the industry any longer (for a variety of reasons, mostly "crunch time and omnipresent background sexism sapped my will to live"), but I still talk to a whooooole lot of friends who are. And I still do game development on my own time; I can attest even just the tools I use as an independent developer have skyrocketed in cost in many areas, much less the sort of stuff entailed in full commercial AAA game dev.
(Albeit with a few pleasant exceptions; Quixel Mixer being free still gives me joy.)
However...
I'm definitely in agreement with this.
I get that this game has a long history of tying in-game items to real-world purchases. Buy a stuffed carbuncle, get a carbuncle minion. Buy a soundtrack, get an orchestrion roll or minion in game. And to some extent, I don't really mind that; buying a soundtrack album and getting an in-game orchestrion roll as a bonus seems a nice perk. (Especially as generally it's an album-specific version of a track that already exists as an orchestrion obtainable in-game.)
But the emotes with the statues are a far cry from an orchestrion roll you get with a relatively-affordable soundtrack; they're very flashy, and precisely the sort of "prestige" thing people would grind in-game to obtain.
I bought the Omega statue because I love those raids, and I am very happy to have the statue here on my desk. (I am also very very glad that they fixed the production quality problems with said statues before mine shipped.) And I do also love the emotes that came with that statue, don't get me wrong. But it's kind of lame that other people who want them would've had to pay quite a bit for a statue that they maybe didn't want just to get the emotes that they did want.
And this is only exacerbated by the fact that the statues quickly go out of stock entirely, potentially for very, very long times. If you want Odin's Zantetsuken emote, even if you're willing to buy the statue to get it, you don't have that option any longer. Same with the emotes for any of the other statues.
And while I don't really want any of the other statues -- maybe Shiva, given the Heavensward story -- I would have happily done something stupidly grindy in-game to get that Zantetsuken emote if I had the option.
I mean, I hate when there's something you find in-game that you realize you can't get because you weren't playing during a specific time when that thing was available to get in-game. (Witness people looking at Garo stuff before they were able to negotiate the return of the Garo tie-in event. Or people who couldn't get the FFXV Regalia mount because they started playing after the event was held. Or anyone looking at PvP seasonal mounts that haven't been available for like... 4 years, or whatever.)
It's even worse if it's something you now can't get and would have had to pay real money for even if you could. That's the sort of thing to induce the worst type of FOMO mindset -- the thought that "if I don't spend this money now, I won't be able to get the thing I want ever."
That's just yikes on a lot of levels.
