The actual answer is that historically we've seen that SE tends to pay more attention to their JP community and the percentile of JP players who have completed this raid tier is leaps and bounds above what NA/EU have done. And plenty of JP players have done this pugging them, really raid finder actually works as intended for them.
Also I just gotta say... SE barely caters to the raiding community at all. I also think you've confused "hardcore" with "raiding." Plenty of raiders are hella casual, unless you consider playing the game for 2-3 hours at a time hardcore. But anyway, SE barely, barely caters to the hardcore community. Which is sad considering they're the most dedicated players, but what they get is a measly FOUR fights per raid tier, and their gear reward is only barely marginally better than if someone just went out all in tome gear. Compare this to all of the casual content we get, dungeons per patch, primals of the hm and ex variety, glamour, housing, not to mention story mode of all things.
I had assumed you had something against statics, but I guess you just have something against hard content in FFXIV period. Which is pretty -- mindboggling? But in a weird alternate reality where SE somehow removed all hard content from the game, what exactly is the point of getting all that tome gear every week for? Do you really need it for playing FFXIV Candyland? That's the real reason you see raiders (including dumb ones like the one in the link you posted) ask for better gear than you get from faceroll content. They're the only ones who need it! For as little as SE gives raiders these days, they're never going to totally fk them over because that would be totally antithetical to the entire kind of MMORPG SE has made from the beginning with FFXI and also with FFXIV too. What you're asking for is chopping off the hard boss at the end of a video game. You're asking them to cut out Ganondorf of Sephiroth, which would be a real head-scratcher for an MMO that is as focused on vertical progression as FFXIV is.
