Whilst I don't entirely disagree - I do think some of it is disingenuous. With the exception of large-scale exploratory content, none of that 'content' really has any substance. Island Sanctuary ended up coming about as substantive as logging in and doing your weekly Custom Delivery or Beast Tribe quest. You logged in, got your populated Excel spreadsheet, populated your workshop and then ignored it for 1-2 weeks. What am I going to do after spending 20 minutes doing 2 Hildibrand quests every 5 months. Roulettes are a core gameplay loop for both casuals and hardcore players. It isn't like they put that there for casual players LOL. Players engaging with the harder content actually have more of a reason to in there just because of the gear requirement of the content they do. PvP isn't really catered to either hardcore or casual players specifically. It's an entirely different niche of the game for people with their own interests regardless of whether they might be casual or hardcore.
What I will say is, I don't think SE favors one of the other. I think they frontload 'hardcore' content, and then backload 'casual' content. So they care about both equally in the long term. I disagree as to say they care a lot more about us than we deserve. They care far too little for what people put into this game, for both 'casual' and 'hardcore' players. XIV is the equivalent of going to your local McDonalds restaurant.
That being said, irrespective of the fact, both hardcore and casual players benefit from having something substantive like zone explorations. Nobody wants to come in for their weekly cookie cutter content.
